Acetylation

Vedclass · Answer

(B) Direct nitration of aniline $(C_6H_5NH_2)$ results in the formation of tarry oxidation products along with nitro derivatives because the $-NH_2$ group is strongly activating and ortho/para-directing.To control the reaction and obtain the desired para-nitroaniline,the $-NH_2$ group is protected by acetylation using acetic anhydride or acetyl chloride to form acetanilide $(C_6H_5NHCOCH_3)$.This reduces the activating effect of the group and prevents oxidation,allowing for controlled nitration.

Before nitration of amino benzene,the $-NH_2$ group is first protected by which of the following processes?
