Vedclass · Answer

(B) The reaction of bromobenzene with $SO_3/H_2SO_4$ (sulphonation) primarily yields the para-substituted product due to steric hindrance at the ortho position,making $A$ = $4$-bromobenzenesulphonic acid.Next,the reaction of $4$-bromobenzenesulphonic acid with $Br_2/Fe$ (electrophilic aromatic substitution) occurs. The $-SO_3H$ group is meta-directing,while the $-Br$ group is ortho/para-directing. The position ortho to the $-Br$ group and meta to the $-SO_3H$ group is the most favored site for the incoming electrophile,leading to $B$ = $2,4$-dibromobenzenesulphonic acid.

In the following series of reactions,identify the major products $A$ and $B$ respectively.
