Primary aromatic amine

Vedclass · Answer

(C) The formation of diazonium salts,known as the diazotization reaction,occurs when a $1^{\circ}$ aromatic amine reacts with nitrous acid $(HNO_2)$ in the presence of an excess of mineral acid (like $HCl$) at a low temperature of $273-278 \ K$. $Ar-NH_2 + HNO_2 + 2HX \xrightarrow{273-278 \ K} Ar-N_2^+X^- + 2H_2O$ Therefore,the correct reactant is a primary aromatic amine.

The diazonium salts are the reaction products in the presence of excess of mineral acid with nitrous acid and:
