Vedclass · Answer

(A) $1$. The reaction of aniline with acetic anhydride $(CH_3CO)_2O$ in the presence of pyridine leads to the formation of acetanilide,which is compound $(A)$. This step protects the $-NH_2$ group to reduce its activating effect and prevent poly-substitution.$2$. Acetanilide undergoes electrophilic aromatic substitution with $Br_2/Fe$ to give $p$-bromoacetanilide as the major product due to steric hindrance at the ortho position.$3$. Finally,hydrolysis of $p$-bromoacetanilide with $H_3O^+$ removes the acetyl group to yield $p$-bromoaniline as the major product $(B)$.

The major product $(B)$ in this reaction is:
