    Which of the following has least ionic radius?

    A) \[{{I}^{+}}\]                                       

    B)  \[{{I}^{3+}}\]

    C)  \[{{I}^{5+}}\]                                    

    D)  \[{{I}^{7+}}\]

    Correct Answer: D

    Solution :

                    The size of cation decreases, with the increasing of magnitude of positive charge. Hence, the order of ionic radius is as: \[{{I}^{+}}>{{I}^{3+}}>{{I}^{5+}}>{{I}^{7+}}\]
