  • 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) \[NO_{2}^{+}\]

    Correct Answer: D

    Solution :

    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.
