Vedclass · Answer

(A) When an alkylbenzene with at least one $\alpha$-hydrogen atom is oxidized with hot alkaline $KMnO_4$,the entire alkyl group is oxidized to a carboxyl group $(-COOH)$ attached to the benzene ring.In the case of $n$-butylbenzene $(C_6H_5-CH_2-CH_2-CH_2-CH_3)$,the $\alpha$-carbon (the carbon directly attached to the benzene ring) possesses two hydrogen atoms.Therefore,the side chain is oxidized to a carboxylic acid group,resulting in the formation of benzoic acid $(C_6H_5COOH)$.
