Vedclass · Answer

(A) The reaction of aniline with acetic anhydride $(CH_3CO)_2O$ leads to the formation of acetanilide $(A)$. This process is known as acetylation. The $-NHCOCH_3$ group is less activating than the $-NH_2$ group due to the resonance of the lone pair of nitrogen with the carbonyl group. This reduces the electron density on the ring,preventing polybromination. When acetanilide $(A)$ is treated with $Br_2$ in $CH_3COOH$,the bulky acetamido group directs the incoming bromine atom primarily to the para position due to steric hindrance at the ortho position. Thus,the major product $B$ is $p$-bromoacetanilide.

In the following sequence of reaction,identify the major product $B$.
