    The isoelectronic pair is:

    A) \[C{{l}_{2}}\,O,\,ICl_{2}^{-}\]            

    B) \[ICl_{2}^{-},Cl{{O}_{2}}\]

    C) \[IF_{2}^{+},I_{3}^{+}\]                 

    D) \[ClO_{2}^{-},ClF_{2}^{+}\]

    Correct Answer: D

    Solution :

    [d] \[ClO_{2}^{-},ClF_{2}^{+}\] Electrons in \[ClO_{2}^{-}=17+(8\times 2)+1=34\] Electrons in \[ClF_{2}^{+}=17+(9\times 2)-1=34\] Isoelectronic pair means having same number of electrons.
