Vedclass · Answer

(C) The Assertion is correct. Aniline is highly reactive and prone to oxidation; therefore,the $-NH_2$ group is protected by acetylation with acetic anhydride to form acetanilide. The Reason is incorrect. The acetyl group $(-COCH_3)$ is an electron-withdrawing group due to resonance with the lone pair of nitrogen,which decreases the electron density on the benzene ring,thereby moderating the reactivity of the ring and preventing the formation of oxidation products.

Assertion : Nitration of aniline can be conveniently done by protecting the amino group by acetylation.
Reason : Acetylation increases the electron density in the benzene ring.
