IUPAC name for the molecule is to be written. Concept introduction: For a molecule that has both, C=C and C ≡ C groups, the IUPAC name indicates both the groups and are called ‘enyne’. The root name is established as the longest carbon chain or largest carbon ring that contains both groups and change the suffix to enyne. The numbering system must be chosen so as to give the minimum locator number for each successive C=C and C ≡ C group. The C=C and C ≡ C groups are given equal priority unless there is a tie between two numbering systems. If there is a tie, the tie is broken by giving priority to the C=C group. A locator number of C=C groups is added immediately before en and a locator number of C ≡ C groups is added immediately before ‘yne. Immediately before the ‘ene’ or ‘yne’ suffix, add a letter ‘a’ followed by the above set of locator numbers, and then add a prefix ‘di, tri’ etc.. to specify the number of double or triple bonds. The substituents attached to the root are named in alphabetical order.
