    The following species will not exhibit disproportionation reaction

    A) \[CI{{O}^{-}}\]           

    B)        \[CIO_{2}^{-}\]

    C) \[CIO_{3}^{-}\]           

    D)        \[CIO_{4}^{-}\]

    Correct Answer: D

    Solution :

    In disproportionation reaction, one element of a compound will simultaneously get reduced and oxidised. In \[ClO_{4}^{-},\] oxidation number of \[Cl\] is and it cannot increase further. So, \[ClO_{4}^{-}\] will not get oxidized and so will not undergo disporportionation reaction.
