    In an octahedral crystal field splitting the number of orbitals pushed down in energy is

    A)  3                                            

    B)  2

    C)   5                                           

    D)  zero

    Correct Answer: A

    Solution :

                     In an octahedral crystal field splitting three \[{{d}_{xy}},{{d}_{{{y}^{2}}}}\]and\[{{d}_{xz}}({{t}_{2g}})\]metal orbitals are lowered in energy and two\[{{d}_{{{x}^{2}}-{{y}^{2}}}}\]and\[{{d}_{{{z}^{2}}}}({{e}_{g}})\]orbitals are raised in energy.
