    In which of the following compounds, the oxidation number of iodine is fractional?

    A)  \[I{{F}_{3}}\]                                    

    B) \[I{{F}_{5}}\]

    C)  \[I_{3}^{-}\]                     

    D)        \[I{{F}_{7}}\]

    Correct Answer: C

    Solution :

    Oxidation number of iodine in given species is as follows; O.N. of iodine in\[I{{F}_{3}}=+\,3\] O.N. of iodine in \[I_{3}^{-}=-\frac{1}{3}\] O.N. of iodine in \[I{{F}_{5}}=+\,5\] O.N. of iodine in \[I{{F}_{7}}=+7\]
