    In an octahedral structure, the pair of d orbitals involved in \[{{d}^{2}}s{{p}^{3}}\] hybridization is             [CBSE PMT 2004]

    A)                 \[{{d}_{{{x}^{2}}}},{{d}_{xz}}\]  

    B)                 \[{{d}_{xy}},{{d}_{yz}}\]

    C)                 \[{{d}_{{{x}^{2}}-{{y}^{2}}}},{{d}_{{{z}^{2}}}}\]  

    D)                 \[{{d}_{xz}},{{d}_{{{x}^{2}}-{{y}^{2}}}}\]

    Correct Answer: C

    Solution :

                    In the formation of \[{{d}^{2}}s{{p}^{3}}\]hybrid orbitals two \[(n-1)d\]orbitals of e.g., set [i.e., \[(n-1)\,d{{z}^{2}}\] and \[(n-1)d{{x}^{2}}-{{y}^{2}}\]orbitals] one ns and three np [\[n{{p}_{x}},n{{p}_{y}}\] and \[n{{p}_{z}}\]]  orbitals combine together and form six \[{{d}^{2}}s{{p}^{3}}\] hybrid orbitals.
