    A complex of certain metal has the magnetic moment of \[4.91\] BM, whereas another complex of the same metal with same oxidation state has zero magnetic moment. The metal ion could be :

    A)  \[M{{g}^{2+}}ion\]               

    B)  \[C{{a}^{2+}}ion\]

    C)  \[Na+ion\]                   

    D)  both \[M{{g}^{2+}}\]and \[C{{a}^{2+}}\]

    Correct Answer: C

    Solution :

    \[{{[\overset{II}{\mathop{Fe}}\,\,{{({{H}_{2}}O)}_{6}}]}^{2+}}\,\,n=4\,\,\,and\,\,\mu =4.9]\] \[{{[\overset{II}{\mathop{Fe}}\,\,{{({{H}_{2}}O)}_{6}}]}^{4-}}\,\,n=0\,\,\,and\,\,\mu =0\]
