According to the IUPAC system of nomenclature -al is attached as a suffix to parent alkane for the naming of aldehydes. The ordinal series are based on ordinal numbers such as the English first, second, third (for numbers higher than 2, the ordinal forms are also used for fractions; only the fraction .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}12 has special forms). The suffix is -ane if all of the carbon-carbon bonds are single bonds (formula CnH2n+2), -ene if at least one carbon-carbon bond is a double bond (formula CnH2n), and -yne if there is at least one carbon-carbon triple bond (formula CnH2n-2). The arrangement (with punctuation) is: 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione, This page was last edited on 7 February 2023, at 22:16. Four prefixes were added. For example, II. Historical Exception. . Links to other areas of the chemistry syllabus. Ionic compounds will follow set of rules, and molecular compounds will follow another. The breadth, depth and veracity of this work is the responsibility of Robert E. Belford, rebelford@ualr.edu. The following table of 24 SI prefixes ranging from 1030 to 1030 are currently recognized for use. *Note: These suffixes, in which the carbon atom is counted as part of the preceding chain, are the most commonly used. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Common nomenclature uses the older names for some organic compounds instead of using the prefixes for the carbon skeleton above. Multiple groups are dichloro-, trichloro-, etc., and dissimilar groups are ordered alphabetically as before. How did you use the result to determine who walked fastest and slowest? There are no exceptions for words comprising technical numerical prefixes, though. So, here we go, introducing the 12 prefixes: - Tera - Giga - Mega - kilo - hecto - deca - deci - centi - mili - micro - nano - pico -. With one fewer oxygen than the "-ate" ion, the acid will have the suffix "-ous." For example, chlorous acid is HClO 2. Two for forming multiples: zetta and yotta. To alleviate this ambiguity, prefixes for binary multiples have been adopted by the International Electrotechnical Commission (IEC) for use in information technology. Parameter. For more information, see our tutorial on naming ionic compounds. Similarly, some are only derived from words for numbers inasmuch as they are word play. The name of the carboxylate anion is derived from that of the parent acid by replacing the "oic acid" ending with "oate." Arrangement in this form: Group of side chains and secondary functional groups with numbers made in step 3 + prefix of parent hydrocarbon chain (eth, meth) + double/triple bonds with numbers (or "ane") + primary functional group suffix with numbers. If there is more than one of the same type of substituent/double bond, a prefix is added showing how many there are (di 2 tri 3 tetra 4 then as for the number of carbons below with 'a' added). Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. The di-, tri- etc. For example, \(\ce{P4O6}\) and \(\ce{P4O10}\) are called phosphorus trioxide and phosphorus pentoxide respectively. This method is especially useful when both groups attached to the oxygen atom are complex.[3]. For example, NO2 would be called nitrogen dioxide, not mononitrogen dioxide. It should have the maximum number of multiple bonds. For example,(CH3)2CHCH2CH2Br is named 1-bromo-3-methylbutane. 2-hydroxypropane-1,2,3-tricarboxylic acid, "IUPAC nomenclature of organic chemistry", Learn how and when to remove this template message, IUPAC nomenclature of inorganic chemistry, International Union of Pure and Applied Chemistry, Functional group Table of common functional groups, International Union of Biochemistry and Molecular Biology, "Table 28(a): Carboxylic acids and related group". Note also that some names are given using other conventions. Was this answer helpful? https://www.nist.gov/pml/owm/metric-si-prefixes. Grouped with the side chains, this gives 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxy. The prefix form is both "carbamoyl-" and "amido-", e.g., HCONH2 methanamide, CH3CONH2 ethanamide. Naming these compounds involves the use of numerical prefixes: Prefix Number Prefix Number mono 1 hexa 6 di 2 hepta 7 tri 3 octa 8 tetra 4 nona 9 penta 5 deca 10 If there is only ONE atom of the first element, you DON'T need a prefix. There is also an IUPAC nomenclature of inorganic chemistry. Numbering of the chain. For Example, CH3CO-R is called Ethanoyl-R. Introduction to Chemistry Prefixes Number of Atoms: Prefixes 1: mono 2: di 3: tri 4: tetra 5: penta 6: hexa 7: hepta 8: octa 9: nona 10: deca The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. The common prefixes are given in this Table. The purpose of organic chemistry nomenclature is to indicate how many carbon atoms are in a chain, how the atoms are bonded together, and the identity and location of any functional groups in the molecule. Nitriles (RCN) are named by adding the suffix -nitrile to the longest hydrocarbon chain (including the carbon of the cyano group). September 2, 2022 by Alexander Johnson A prefix to the name comes before the molecule. Here is a list of common Greek prefixes used in naming polygons and polyhedra. 1 mono; 2 di; 3 tri; 4 tetra; 5 penta; 6 hexa; 7 hepta; 8 octa; 9 ennea; The root names of hydrocarbon molecules are based on whether they form a chain or ring. Each carbon atom participates in 4 chemical bonds. Be aware, hydrocarbons found as rings (aromatic hydrocarbons) are named somewhat differently. LKS2 Non-Chronological Reports . The groups are on carbon atoms 3 and 9. The smaller number is always used, not the sum of the constituents numbers. For example, CH3CH(OH)COOH (lactic acid) is named 2-hydroxypropanoic acid with no "1" stated. For real large or small numbers, the convention is to place a number with between 1 and 999 in front of the SI prefix, and use the appropriate prefix to show the value. These are given according to their empirical formulas. 4) Prefix the root word with the infix "cyclo" if the parent chain is cyclic; or with the infix "spiro" if it is a spiro compound; or with the infix "bicyclo" if the compound is bicyclic. The groups are on carbon atoms 3 and 9. \[ \begin{align} 1,330,000,000m& =1.33\times 10^{9}m =1.33 \; gigameters\nonumber \\13,300,000,000m& =13.3 \times 10^{9}m=13.3 \;gigameters\nonumber\\ 133,000,000,000m& =133\times 10^{9}m = \; 133 \; gigameters\end{align}\]. The prefix system is used when both elements are non-metallic. The second system, the stock system, uses oxidation numbers to represent how the electrons are distributed through the compound. Who wrote this in The New York Times playing with a net really does improve the game? prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. Prefixes in molecular compounds are decided by the number of atoms of each element in the compound. (6.8k) $6.98. Because it contains carbon-carbon double bonds, the -ene suffix is present. Where an acid has both a systematic and a common name (like CH3COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. 1. These compounds are neutral overall. Prefixed substituents are ordered alphabetically (excluding any modifiers such as di-, tri-, etc. The first few are: For example, the simplest alkane is CH4 methane, and the nine-carbon alkane CH3(CH2)7CH3 is named nonane. Dont get frustrated with yourself if you dont understand it right away. Number if forward and backward; PREFIXES NUMBER OF CARBON ATOMS WORD ROOT/PREFIX. Functional class IUPAC nomenclature may also be used in the form of alkyl cyanides. We have all heard of SI prefixes, for example you may have a 16 Gbyte flash drive, where the G stands for giga and means 109, and that is a much more convienent way of expressing the number of bytes than using the floating number of 16,000,000,000 bytes. See, They occur in words in the same languages as the original number word, and their respective derivatives. In general, carboxylic acids are named with the suffix -oic acid (etymologically a back-formation from benzoic acid). The aldehyde group is always attached at the end of the main carbon chain, and hence the 1 st position in the . 3 is less than 15, therefore the ketones are numbered 3 and 9. Covalent compounds have Greek numerical prefixes to indicate the number of atoms. This makes it a prime target for teachers to test. Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. In the latter case, the carbon atoms in the carboxyl groups do not count as being part of the main chain, a rule that also applies to the prefix form "carboxy-". springhill suites knoxville at turkey creek; p0171 . Capitalization. If the oxygen is not attached to the end of the main alkane chain, then the whole shorter alkyl-plus-ether group is treated as a side-chain and prefixed with its bonding position on the main chain. Thus CH3OCH(CH3)2 is 2-methoxypropane. (But this is not necessarily the final grouping, as functional groups may be added in between to ensure all groups are listed alphabetically.). Full coverage of each topic and sub-topic. Chart dimensions: 216 mm by 279 mm (8.5 in by 11in). Number of Carbon 1 2. [B] There is also an international set of metric prefixes, which are used in the metric system and which for the most part are either distorted from the forms below or not based on actual number words. They would be called "6,13-diene", but the presence of alkynes switches it to 6,13-dien. Organic Chemistry Prefixes and Suffixes. (Peta- is word play on penta-, for example. Section 7 1 Naming and Writing Formulas for Molecular Compounds The prefix in the name of a binary molecular compound tells how many atoms of each element are present in each molecule of the compound to Some of the examples show the variations. The convention of writing a zero before the decimal point is used to ensure that the quantity is appropriately interpreted. Identification of the remaining functional groups, if any, and naming them by their ionic prefixes (such as hydroxy for -OH, oxy for =O, oxyalkane for O-R, etc.). Organic Chemistry Prefixes For example: In many European languages there are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. It is not an SI prefix, but is a common unit of length that is used when describing bond lengths and distances between atoms (and ions) in a crystal. Second element; named as if it were an anion (-ide suffix) always gets a prefix mono - 1 penta - 5 octa - 8 di - 2 hexa - 6 nona - 9 tri - 3 hepta - 7 deca - 10 tetra - 4 C. Naming Acids; Binary Acids (two elements - hydrogen + one other) a. prefix "Hydro" + root of second element + "ic" suffix . Understandably, the rules for naming organic compounds are a lot more complex than for normal, small molecules. Webmaster | Contact Us | Our Other Offices, Created January 13, 2010, Updated December 21, 2022, Two prefixes for forming submultiples were added: femto and atto. Bibliography of IUPAC Recommendations on Organic Nomenclature, "Improving the Quality of Published Chemical Names with Nomenclature Software", American Chemical Society, Committee on Nomenclature, Terminology & Symbols, https://en.wikipedia.org/w/index.php?title=IUPAC_nomenclature_of_organic_chemistry&oldid=1138073631, Articles needing additional references from April 2019, All articles needing additional references, Articles with unsourced statements from January 2012, Wikipedia articles needing clarification from February 2016, Creative Commons Attribution-ShareAlike License 3.0, It should have the maximum number of substituents of the suffix functional group. In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them. 2. Prefix poly- The prefix poly- means many, much, or in great number. Helmenstine, Anne Marie, Ph.D. "Organic Chemistry Prefixes and Suffixes." The Merriam-Webster Collegiate Dictionary provides two common pronunciations for the scientific term gigawatt. A prefix to the name comes before the molecule. { "2.01:_Mathematical_Fundamentals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.02:_Algebra_Review" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.03:_Numbers" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.04:_Units_of_Measurement" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.05:_Measured_Numbers_and_Significant_Digits" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.06:_Scientific_Notation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.07:_SI_Prefixes" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.08:_Unit_Conversions_and_Dimensional_Analysis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.09:_Fractions_and_Percent" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.10:_Graphing_and_Temperature_Conversions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "00:_General_Information" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Introduction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Mathematical_Fundamentals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Atoms_and_Elements" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Compounds_and_Molecules" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Counting_Molecules_through_Measurements" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Stoichiometry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_Solution_Chemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "09:_Gases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "10:_Thermodynamics" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "authorname:belfordr" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FUniversity_of_Arkansas_Little_Rock%2FChem_1300%253A_Preparatory_Chemistry%2FLearning_Modules%2F02%253A_Mathematical_Fundamentals%2F2.07%253A_SI_Prefixes, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), 2.8: Unit Conversions and Dimensional Analysis, status page at https://status.libretexts.org, Elena Lisitsyna& Vincent Belford(H5P interactive modules). For example, CH3COCl is ethanoyl chloride. In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound. Additional details for the use of functional prefixes and suffixes are found in Section R-4 (Name Construction). Alternatively, the suffix "-carboxylic acid" can be used, combined with a multiplying prefix if necessary mellitic acid is benzenehexacarboxylic acid, for example. The cardinal series are derived from cardinal numbers, such as the English one, two, three. Metric or SI (Le Systme International d'Units) prefix are based on powers of ten. 3. A .gov website belongs to an official government organization in the United States. According to the current version of Nomenclature of Organic Chemistry - IUPAC Recommendations and Preferred Names 2013 (Blue Book), simple prefixes (simple substituent groups consisting of just one part that describes an atom, or group of atoms as a unit, for example methyl, cyclohexyl, and isopropyl) are arranged alphabetically disregarding any Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. A prefix to the name comes before the molecule. These non-systematic names are often derived from an original source of the compound. If just one atom of the first element is in the formula, omit the prefix mono- for that element. Values of quantities are expressed using Arabic symbols for numbers paired with a unit symbol, often with a prefix symbol that modifies unit magnitude. Department of Chemistry and Biochemistry Fayetteville, Arkansas 72701. Numbers identify the substituent position. Geometric Isomer Definition (Cis-Trans Isomers), What Happens to Candle Wax When a Candle Burns, Common Functional Groups in Organic Chemistry, The Definition of Ortho, Meta, and Para in Organic Chemistry, Definition of Carboxyl Group in Chemistry. 2 Brief summary of contents of 'Complete course for students'. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. R-oxycarbonyl-halocarbonyl-carbamoyl--imido-amidino-, -R-oate-oyl halide*-amide*-imide*-amidine*. CH3F3N+ is trifluoromethylammonium. The names of the first four alkanes were derived from methanol, ether, propionic acid and butyric acid, respectively. The common name for an aldehyde is derived from the common name of the corresponding carboxylic acid by dropping the word acid and changing the suffix from -ic or -oic to -aldehyde. what type of danger zone is needed for this exercise. "cyclohexyl-") or for benzene, "phenyl-". You will need the prefixes in order to give a proper name of many compounds. However, these compounds have many positively and negatively charged particles. The name of each substitution is prefixed to the hydride cation name. When numbering from right to left, the ketone groups are numbered 15 and 21. Dont worry about those rules for now its just something to keep in the back of your mind! Identification of the side-chains. Names of hydrocarbon molecules are based on the number of carbon atoms in the molecule and the type of bond between them. Citric acid serves as an example: it is formally named 2-hydroxypropane-1,2,3-tricarboxylic acid rather than 3-carboxy-3-hydroxypentanedioic acid. Alkenes are named for their parent alkane chain with the suffix "-ene" and an infixed number indicating the position of the carbon with the lower number for each double bond in the chain: CH2=CHCH2CH3 is but-1-ene. novem-Prefix Prefix meaning Sample words; novem-9: novena: prayers said over nine days: deka- or deca-10: decade: a period of 10 years: cent- Amides (RCONH2) take the suffix "-amide", or "-carboxamide" if the carbon in the amide group cannot be included in the main chain. As there are two, we write 3,9-dione. You also need to know them to figure out the formula from their names. There are two ethyl- groups. with each formula unit. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Rachel Lynette. They are modifiers on the root word that tell us the unit of measure. You use a variety of different compounds in every day life! Metric Prefixes. If the cationic center of the hydride is not a halogen, chalcogen or pnictogen then the suffix "-ium" is added to the name of the neutral hydride after dropping any final 'e'. Acyl groups are named by stripping the -ic acid of the corresponding carboxylic acid and replacing it with -yl. If you type 1,200,000 into your calculator and press ENG, it gives 1.2 x 106, so 1,200,000 bytes of memory on a memory stick would be 1.2 MBytes (you do not say 1,200 kBytes). It means "on the right side". The result is you can express any number with between 1 and 999 values to the left of the decimal, followed by the appropriate SI prefix. Flash cards that go from SI prefix name to value. How to Name Chemical Compounds. As with aldehydes, the carboxyl functional group must take the "1" position on the main chain and so the locant need not be stated. Use prefixes appropriately to indicate the number of each kind of atom. A challenge for you to think more deeply . So the ENG function quickly converts numbers to values that can easily be expressed with SI prefixes. The learning outcomes (i.e. In English and many other languages, they are used to coin numerous series of words. The prefix of 9 is "non" For example, a nonagon is a two-dimensional shape with 9 sides. 5) Finally add prefix(es) to the IUPAC name, if there are side chains or substituents on the parent chain. The order of remaining functional groups is only needed for substituted benzene and hence is not mentioned here. Each alkane name is built from a prefix (first part) and a suffix (ending). You will also learn the basics of these chemistry prefixes and how they are applicable in the real world today! Ideally, every possible organic compound should have a name from which an unambiguous structural formula can be created. Each element, carbon and. Numeric prefixes (mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca) These are ONLY used for the following: -Metal-containing acids and acid ions: the prefix ONLY goes on the hydrogen (mono is dropped) . This chronological summary highlights these developments. What does the prefix D mean in chemistry? PDF. H5C+ is methanium, HO-(O+)-H2 is dioxidanium (HO-OH is dioxidane), and H2N-(N+)-H3 is diazanium (H2N-NH2 is diazane). Prefix Symbol Meaning ; deci: d: 10-1 centi: c 10-2 milli: m 10-3 micro: along with a chart of SI prefixes and more advanced, derived units (such as the joule and watt). Eight original SI prefixes were officially adopted: deca, hecto, kilo, myria, deci, centi, milli, and myrio, derived from Greek and Latin numbers. The hydrons are not found in heavier isotopes, however. However, many organic cations are obtained by substituting another element or some functional group for a hydrogen. When you want to express some large or small quantities, you may also find these prefixes useful. The prefix of the molecule's name is based on thenumber of carbon atoms. Numerical prefixes are not restricted to denoting integers. For example, H 2 C=O is named as per the IUPAC system as methanal, commonly known as formaldehyde. She has taught science courses at the high school, college, and graduate levels. A benefit of the SI (International System of Units) is that written technical information is effectively communicated, transcending the variations of language including spelling and pronunciation. The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule. If there is ambiguity in the position of the substituent, depending on which end of the alkane chain is counted as "1", then numbering is chosen so that the smaller number is used. Two prefixes for forming submultiples were added: femto and atto. * SI base or derived units with special names may be used. If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH2COOH is 3-oxopropanoic acid. Note, on the flash cards you can skip a card by clicking. So we would say 16Gigabytes and not 16,000 Mbytes of 16,000,000 kbytes.
