    For nitration of benzene, we require :

    A)  conc. \[HN{{O}_{3}}+\] conc. \[{{H}_{2}}S{{O}_{4}}\]

    B)  conc. \[HN{{O}_{3}}\]

    C)  cone. \[{{H}_{2}}S{{O}_{4}}\] fuming \[HN{{O}_{3}}\]

    D)  \[KN{{O}_{2}}\]

    Correct Answer: A

    Solution :

    Benzene is nitrated by mixture of cone. \[HN{{O}_{3}}\] and cone.\[{{H}_{2}}S{{O}_{4}}\] . Benzene derivatives having groups like -OH can be nitrated by cone. \[HN{{O}_{3}}\] alone.
