    Arrange    m-nitrochlorobenzene   (I) 2, 4 dinitrochloro-benzene (II) p-nitrochlorobenzene (III) according to reactivity with sodium ethoxide.

    A) \[I>II>III\]                          

    B) \[III>I>II\]

    C) \[II>III>I\]                          

    D) \[II=III>I\]

    Correct Answer: C

    Solution :

    m-nitrochlorobenzene is however less reactive than the p-nitrochlorobenzene since the \[N{{O}_{2}}\] group at m-position can't stabilize the intermediate carbonion by resonance. Thus, the correct option is II > III > I.
