    Amongst the following ions» which one has the highest paramagnetism?            

    A)  \[{{[Cr{{({{H}_{2}}O)}_{6}}]}^{3+}}\]

    B)  \[{{[Fe{{({{H}_{2}}O)}_{6}}]}^{2+}}\]

    C)  \[{{[Cu{{({{H}_{2}}O)}_{6}}]}^{2+}}\]

    D)  \[Zn{{({{H}_{2}}O)}_{6}}{{]}^{2+}}\]

    Correct Answer: C

    Solution :

                    \[{{[Fe{{({{H}_{2}}O)}_{6}}]}^{2+}}\]  ion   has   maximum paramagnetism as it has maximum number , of unpaired electrons (i.e., 4)
