The IUPAC names of the compounds are: (a) 3-Methylbutanoic acid (b) 4-Bromopentanoic acid (c) 2-Ethylpentanoic acid (d) (Z)-Hex-4-enoic acid (e) 2,4-Dimethylpentanenitrile (f) cis- 1 ,3-Cyclopentanedicarboxylic acid
Work Step by Step
The IUPAC rules for naming carboxylic acids and nitriles are: 1. Count the number of carbon atoms in the longest chain starting from the carbon of the carboxylic group or the nitrile group. 2. Count the number of substituents, and indicate their point of attachment to the main chain. 3. The chain containing the carboxylic acid group as a functional group is given the suffix -oic acid while the chain containing the nitrile group as a functional group is given the suffix -nitrile.
