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

    A) \[R{{b}^{+}}\]                                   

    B) \[C{{s}^{+}}\]

    C)  \[Li\]                                    

    D) \[N{{a}^{+}}\]

    Correct Answer: B

    Solution :

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