Anisole

Vedclass · Answer

(C) Alkaline $KMnO_4$ is a strong oxidizing agent that oxidizes alkyl side chains attached to a benzene ring to a carboxylic acid group $(-COOH)$.$1$. Toluene $(C_6H_5CH_3)$ oxidizes to benzoic acid $(C_6H_5COOH)$.$2$. Acetophenone $(C_6H_5COCH_3)$ oxidizes to benzoic acid.$3$. Benzyl alcohol $(C_6H_5CH_2OH)$ oxidizes to benzoic acid.$4$. Anisole $(C_6H_5OCH_3)$ is an ether. Ethers are generally inert towards oxidation by alkaline $KMnO_4$ under these conditions,as the methoxy group does not possess the required benzylic hydrogen atoms or the reactivity to be oxidized to a carboxyl group.

Which of the following compounds will not give benzoic acid upon boiling with alkaline $KMnO_4$ followed by acidification?
