Vedclass · Answer

(A) The structure is $CH_3-CH(CH_3)-CO-COOH$. $1$. Identify the principal functional group: The carboxylic acid group $(-COOH)$ has higher priority than the ketone group $(>C=O)$. $2$. Number the carbon chain starting from the carboxylic acid carbon as $C-1$. $3$. The chain is $C_1(OOH)-C_2(=O)-C_3(H)(CH_3)-C_4(H_3)$. $4$. At $C-2$,there is an oxo group. At $C-3$,there is a methyl group. $5$. The parent chain has $4$ carbons,so it is a butanoic acid derivative. $6$. The $IUPAC$ name is $3-$methyl$-2-$oxobutanoic acid.
