Vedclass · Answer

(A) The reaction of $p$-aminobenzenesulfonic acid with $HNO_2$ produces a diazonium salt intermediate. In the presence of acetic anhydride or similar conditions (often implied in such reaction schemes),the diazonium group can form a diazo-ester linkage. Product $A$ is the diazo-ester formed from the reaction. When this intermediate reacts with aniline $(C_6H_5NH_2)$,it undergoes a coupling reaction to form an amino-azo compound $(B)$,specifically $p$-aminoazobenzene-sulfonic acid derivative.

Products $A$ and $B$ formed in the following reactions are respectively:
$p$-aminobenzenesulfonic acid + $HNO_2$ $\longrightarrow$ $A$ $\xrightarrow{C_6H_5NH_2}$ $B$
