Question

Name the following carboxylic acid derivatives, giving both a common name and IUPAC name where possible.

(a) PhCOOCH₂CH(CH₃)₂:

Common Name: __________
IUPAC Name: __________
a) Phenyl acetate, 2-dimethyl
b) Phenyl formate, 2-dimethyl
c) Phenyl acetate, 2-methyl
d) Phenyl acetate, 2-ethyl

Answer 1

The common name for the compound PhCOOCH₂CH(CH₃)₂ is phenyl acetate, and the IUPAC name is 2-methylprop-2-enoic acid.

Step-by-step explanation:

The common name for the compound PhCOOCH₂CH(CH₃)₂ is phenyl acetate, and the IUPAC name is 2-methylprop-2-enoic acid. The common name is derived from the name of the functional group attached to the carboxylic acid, which in this case is an ester.

The IUPAC name follows the rules of nomenclature for carboxylic acids, where the longest hydrocarbon chain containing the carboxylic acid group is chosen as the parent name with the suffix -oic acid. Additionally, the number of substituents and their positions are included in the name.
