    For a tetrahedral complex \[{{[MC{{l}_{4}}]}^{2-}}\], the spin-only magnetic moment is 3.83 BM. The element M is:

    A)  \[Co\]   

    B)                                     \[Cu\]

    C)  \[Mn\]        

    D)                                     \[Fe\]

    Correct Answer: A

    Solution :

                It is high spin complex as \[C{{l}^{-}}\] is weak field effect ligand. In \[{{[CoC{{l}_{4}}]}^{2-}}\] oxidation state of Co is +2 in which 3 unpaired electrons are present which gives the spin-only magnetic moment equal to 3.83 BM.
