    The standard reduction potential of\[L{{i}^{+}}/Li,B{{a}^{2+}}/Ba,\,N{{a}^{+}}/Na\]and \[M{{g}^{2+}}/Mg\]are--\[-3.05,-2.73,-2.71\]and \[-2.37\]volts respectively Which one of the following is strongest oxidising agent?

    A)  \[N{{a}^{+}}\]             

    B)  \[L{{i}^{+}}\]

    C)  \[B{{a}^{2+}}\]                    

    D)  \[M{{g}^{2+}}\]

    Correct Answer: D

    Solution :

     The strongest oxidising agent is one which has maximum tendency to gain electrons, i.e. whose \[{{E}^{o}}_{red}\] is maximum
