Vedclass · Answer

(C) In the nitration of aromatic compounds,a mixture of concentrated nitric acid $(HNO_3)$ and concentrated sulfuric acid $(H_2SO_4)$ is used. Concentrated $H_2SO_4$ acts as a catalyst and facilitates the formation of the electrophile,the nitronium ion $(NO_2^+)$,by protonating the nitric acid molecule. The reaction is: $HNO_3 + 2H_2SO_4 \rightleftharpoons NO_2^+ + H_3O^+ + 2HSO_4^-$. Thus,its primary role is to generate the nitronium ion.

In the nitration mixture,concentrated sulfuric acid $(H_2SO_4)$ is used as:
