Vedclass · Answer

(D) When alkyl benzenes (like ethyl benzene) are treated with strong oxidizing agents such as alkaline $KMnO_4$,the alkyl side chain is oxidized to a carboxylic acid group $(-COOH)$ attached to the benzene ring,regardless of the length of the alkyl chain,provided that the benzylic carbon has at least one hydrogen atom.In the case of ethyl benzene $(C_6H_5-CH_2-CH_3)$,the benzylic carbon has two hydrogen atoms,so it undergoes oxidation to form benzoic acid $(C_6H_5-COOH)$.

The compound formed as a result of oxidation of ethyl benzene by $KMnO_4$ is
