Vedclass · Answer

(B) The starting material is acetanilide. $1$. Reaction with $Br_2/AcOH$: The $-NHCOCH_3$ group is strongly activating and ortho/para-directing. Due to the steric hindrance of the bulky acetamido group,the para-substitution is favored,yielding $4$-bromoacetanilide as the major product $A$. $2$. Reaction with $LiAlH_4$: $LiAlH_4$ is a strong reducing agent that reduces the amide group $(-NHCOCH_3)$ to an amine group $(-NHCH_2CH_3)$. Thus,acetanilide is reduced to $N$-ethylaniline,which is the major product $B$.

The major products $A$ and $B$ from the following reactions are:
