Vedclass · Answer

(A) The reaction is an example of the Etard reaction modification using acetic anhydride and chromic oxide.Step $1$: $4-$Nitrotoluene reacts with acetic anhydride and $CrO_3$ at $273-278 \ K$ to form a gem-diacetate derivative $(X)$.Step $2$: The gem-diacetate derivative $(X)$ undergoes acid-catalyzed hydrolysis $(H_3O^{+} / \Delta)$ to yield $4-$nitrobenzaldehyde $(Y)$.
