Vedclass · Answer

(C) The reaction involves the oxidation of alkyl side chains attached to a benzene ring using alkaline $KMnO_4$ followed by acidification. In the given reactant,$p$-methylacetophenone $(CH_3-C_6H_4-COCH_3)$,both the methyl group $(-CH_3)$ and the acetyl group $(-COCH_3)$ are attached to the benzene ring. Alkaline $KMnO_4$ oxidizes alkyl groups attached to the benzene ring to carboxylic acid groups $(-COOH)$,provided there is at least one benzylic hydrogen. The methyl group $(-CH_3)$ is oxidized to $-COOH$. The acetyl group $(-COCH_3)$ is also oxidized to $-COOH$ because the carbon atom adjacent to the benzene ring (the carbonyl carbon) is bonded to a methyl group,which effectively acts as a site for oxidation,leading to the formation of terephthalic acid (benzene$-1,4-$dicarboxylic acid).

The major product of the following reaction is:
