Vedclass · Answer

(A) The given structure is $Ph-CH=CH-COOH$.In this molecule,the principal functional group is the carboxylic acid $(-COOH)$,which is assigned position $1$.The longest carbon chain containing the double bond and the carboxylic acid group consists of $3$ carbon atoms,hence the parent alkane is $propane$ (prop-).The double bond starts at position $2$,so it is named $prop-2-enoic$ acid.The phenyl group $(Ph-)$ is attached to the $3^{rd}$ carbon atom.Therefore,the $IUPAC$ name is $3-phenylprop-2-enoic$ acid.

The $IUPAC$ name of $Ph-CH=CH-COOH$ is:
