    Which of the following do not show disproportionation reaction? \[ClO_{4}^{-},\,{{F}_{2}},\,C{{l}_{2}},\,ClO_{2}^{-},\,ClO_{2}^{-},\,{{P}_{4}},\,{{S}_{8}}\] and \[Cl{{O}^{-}}\]

    A) \[ClO_{2}^{-},\,ClO_{4}^{-},\] and \[Cl{{O}^{-}}\]

    B) \[{{F}_{2}}\] only

    C) \[{{F}_{2}}\] and \[ClO_{4}^{-}\]

    D) \[ClO_{4}^{-}\] only

    Correct Answer: C

    Solution :

    [c] \[{{F}_{2}}\] being most electronegative element cannot exhibit any positive oxidation state. In \[ClO_{4}^{-}\]chlorine is present in its highest oxidation state i.e +7. Therefore it does not show disproportionation reaction.
