Question

In diazotisation reaction of aniline with NaNO2 and HCl, an excess of HCl is used to (A) suppress the formation of acetanilide (B) suppress the concentration of free aniline available for coupling (C) maintain the pH of the reaction (D) prevent the formation of anilinium ion

Tardigrade Admin · Accepted Answer

Excess of hydrochloric acid avoids the possibility of coupling of coupling reaction by leaving no aniline for coupling reaction

Q. In diazotisation reaction of aniline with $N a N O_{2}$ and $H Cl$ , an excess of $H Cl$ is used to

suppress the formation of acetanilide

suppress the concentration of free aniline available for coupling

maintain the $p H$ of the reaction

prevent the formation of anilinium ion
