Vedclass · Answer

(B) $1$. The reaction of aniline with acetic anhydride ($CH_3CO)_2O$ is an acetylation reaction,which protects the amino group and forms acetanilide $(A)$.$2$. The acetamido group $(-NHCOCH_3)$ is ortho/para directing. Due to steric hindrance,the para-substituted product is the major product.$3$. Reaction of acetanilide with $Br_2$ in $CH_3COOH$ at room temperature leads to electrophilic aromatic substitution,yielding $p$-bromoacetanilide $(B)$ as the major product.

The major products $A$ and $B$ formed in the following reaction sequence are :
