Vedclass · Answer

(A) The structure is $Ph-CH_{2}-CH_{2}-COOH$. To name this compound according to $IUPAC$ rules, we identify the longest carbon chain containing the carboxylic acid group as the parent chain. The carbon atom of the $-COOH$ group is assigned position $1$. The chain consists of $3$ carbons, so the parent alkane is propane. The carboxylic acid suffix is $-oic$ acid. There is a phenyl group attached to the $3^{rd}$ carbon atom. Therefore, the correct name is $3-$phenylpropanoic acid.

In the $IUPAC$ system, $PhCH_{2}CH_{2}CO_{2}H$ is named as
