Vedclass · Answer

(C) The structure $C_6H_5CH=CHCOOH$ consists of a phenyl group attached to a three-carbon chain containing a carboxylic acid group and a double bond.The longest carbon chain containing the carboxylic acid group has $3$ carbon atoms,making it a derivative of propanoic acid.The double bond starts at the $2^{nd}$ carbon atom,so it is named prop$-2-$enoic acid.$A$ phenyl group $(-C_6H_5)$ is attached to the $3^{rd}$ carbon atom.Combining these,the $IUPAC$ name is $3-$phenylprop$-2-$enoic acid.Its common name is cinnamic acid.
