Vedclass · Answer

(B) The reaction involves the oxidation of alkyl groups attached to a benzene ring using $KMnO_4$ in an acidic medium under heating. Any alkyl group attached to the benzene ring,provided it has at least one benzylic hydrogen atom,is oxidized to a carboxylic acid group $(-COOH)$. In the given reactant,$1$-ethyl-$3$-methylbenzene,both the ethyl group $(-CH_2CH_3)$ and the methyl group $(-CH_3)$ have benzylic hydrogen atoms. Therefore,both groups are oxidized to $-COOH$ groups,resulting in benzene-$1,3$-dicarboxylic acid (isophthalic acid).

Predict the major product of the reaction of $1$-ethyl-$3$-methylbenzene with $KMnO_4$ in an acidic medium under heating.
