    The species responsible for nitraction is:

    A) \[NO_{2}^{+}\]                                

    B) \[N{{O}_{3}}\]

    C) \[N{{O}_{2}}\]                                  

    D)  all the above

    Correct Answer: A

    Solution :

    The nitration takes place in presence of \[{{H}_{2}}S{{O}_{4}}\cdot {{H}_{2}}S{{O}_{4}}\]is responsible for the generation of nitronium ion\[\overset{+}{\mathop{(N{{O}_{2}})}}\,\] which is responsible for nitration. \[HN{{O}_{2}}+2{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}{{H}_{2}}{{O}^{+}}2HSO_{4}^{-}\]\[\underset{nitronium\,\,ion}{\mathop{+NO_{2}^{+}}}\,\]
