Statement $I$ is correct but Statement $II$ is incorrect

Vedclass · Answer

(B) In the nitration of benzene,concentrated $H_2SO_4$ and $HNO_3$ are used as reagents,which generate the electrophile $NO_2^+$ in the following steps:$H_2SO_4 + HNO_3 \rightleftharpoons HSO_4^- + H_2O^+-NO_2$$H_2O^+-NO_2 \rightleftharpoons H_2O + NO_2^+$Statement $I$ is correct as it shows the dissociation of the protonated nitric acid into water and the nitronium ion $(NO_2^+)$.Statement $II$ is incorrect because Lewis acids (like $AlCl_3$,$FeBr_3$) are used to promote electrophilic substitution by generating electrophiles,not Lewis bases.
