    Which of the following alkali metal ions has lowest ionic mobility in aqueous solution?

    A)  \[R{{b}^{+}}\]          

    B)  \[C{{s}^{+}}\]

    C)  \[L{{i}^{+}}\]          

    D)  \[N{{a}^{+}}\]

    Correct Answer: B

    Solution :

    The order of ionic conductance in aq. solution is as follows: \[L{{i}^{+}}(aq.)<N{{a}^{+}}(aq.)<{{K}^{+}}(aq.)<R{{b}^{+}}(aq.)\] \[<C{{s}^{+}}(aq.)\]
