• question_answer The nitration of a compound is due to the [Pb. PMT 2004] A) $N{{O}_{2}}$ B) $N{{O}_{3}}$ C) NO D) $NO_{2}^{+}$

The process of nitration takes place as below $HON{{O}_{2}}+2{{H}_{2}}S{{O}_{4}}$ ⇌ ${{H}_{3}}{{O}^{+}}+2HSO_{4}^{-}+\underset{(\text{nitronium ion})}{\mathop{NO_{2}^{+}}}\,$ The electrophile responsible for nitration is $NO_{2}^{+}$ ion.
