Vedclass · Answer

(C) The reaction involves the oxidation of alkylbenzenes using strong oxidizing agents like $KMnO_4$ in an acidic medium.Any alkyl group attached to the benzene ring,provided it has at least one benzylic hydrogen atom,is oxidized to a carboxylic acid group $(-COOH)$ regardless of the length of the alkyl chain.In the given reactant,$1$-ethyl-$4$-methylbenzene,both the methyl group $(-CH_3)$ and the ethyl group $(-CH_2CH_3)$ have benzylic hydrogen atoms.Therefore,both alkyl groups are oxidized to carboxylic acid groups,resulting in the formation of benzene-$1,4$-dicarboxylic acid,also known as terephthalic acid.The correct option is $C$.
