Vedclass · Answer

(D) Aniline is highly reactive and sensitive to oxidation. During nitration,the $-NH_2$ group is protonated in the acidic medium to form the anilinium ion $(-NH_3^+)$,which is meta-directing. To obtain ortho and para products and to protect the amino group from oxidation,it is acetylated using acetic anhydride ($CH_3CO)_2O$ to form acetanilide. After nitration,the acetyl group is removed by hydrolysis.

The reagent used for the protection of the amino group during the nitration of aniline is:
