Of course, a wide range of traditional names, semisystematic or trivial, are also in use for a core group of common compounds. IUPAC Rules for Naming Alkenes I. Use IUPAC Rules for Naming Alkanes as starting point.

Nomenclature rules for other types of compounds are given in Chapter 7. Our books collection hosts in multiple locations, allowing you to get the most less latency time to download any An invaluable source of information for organic chemists everywhere and the definitive guide for scientists working in academia or industry, for scientific publishers of books, journals and databases, and for organisations requiring internationally approved nomenclature in a legal or regulatory environment.iupac nomenclature of organic chemistry is available in our digital library an online access to it is set as public so you can get it instantly. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name.
Functional groups are defined as specific atoms, group of atoms or ions which are part of a larger hydrocarbon chain and impart characteristic properties to the compounds.A molecule of ethyl alcohol contains two carbon atoms, so the root word should be “eth”.It is saturated so the primary suffix should be “ane” but as there is a functional group (alcohol) “–OH” in the molecule, remove the “e” from the name of the molecule and add the secondary suffix “ol”.Therefore, the IUPAC name of ethyl alcohol is “ethanol”.The IUPAC name of the propanaldehyde molecule can be written as Propanal,Root word + Primary suffix + Secondary suffix: PropanalThe IUPAC name of acetone can be written as propanone.Root word + Primary suffix + Secondary suffix : PropanoneAnd IUPAC name of acetic acid can be written as ethanoic acidRoot word + Primary suffix + Secondary suffix: Ethanoic acidThe parts of the name that precede the root word are called prefixes. For such hydrocarbons, the primary suffix “ene” should be added to the root word.Example: The IUPAC name of a molecule which contains double bond between carbon atoms.In writtingnomeclature of alkenes according to IUPAC, it is important to mention the position of double for the molecules which contain more than three carbon atoms.Hydrocarbons that contain a triple bond between carbon atoms are known as alkynes and for naming such hydrocarbons the primary suffix “yne “should be added.Example: The IUPAC name of a molecule which contains triple bond between carbon atoms.In writtingnomeclature of alkynes according to IUPAC, it is important to mention the position of triple bond for the molecules which contain more than three carbon atoms.A secondary suffix indicates the functional group present in the carbon compound. The suffix is again divided into primary and secondary.Primary suffix indicates the degree of saturation or unsaturation in the basic skeleton and is added immediately after the root word.Primary suffix + Root word → Saturated or unsaturated carbon chainFor saturated hydrocarbons, the primary suffix “ane” should be added.Example: The IUPAC name of a molecule which contains single bond between carbon atoms.Hydrocarbons containing double bonds are known as alkenes.
