    The nitration of a compound is due to the:

    A)  \[N{{O}_{2}}\]            

    B)  \[N{{O}_{3}}\]

    C)  \[NO\]            

    D)  \[{{N}^{+}}{{O}_{2}}\]

    Correct Answer: D

    Solution :

     The process of nitration takes place as below:- \[\underset{(HN{{O}_{3}})}{\mathop{HON{{O}_{2}}}}\,+2{{H}_{2}}S{{O}_{4}}\overset{+}{\mathop{{{H}_{3}}O}}\,+\overset{-}{\mathop{2{{H}_{2}}S{{O}_{4}}}}\,\] \[\underset{nitronium\text{ }ion}{\mathop{+\overset{+}{\mathop{N{{O}_{2}}}}\,}}\,\] The electrophile responsible for nitration is\[\overset{+}{\mathop{N{{O}_{2}}}}\,\]ion.
