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

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

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

    C) \[{{d}_{{{z}^{2}}}},{{d}_{xz}}\]

    D) \[{{d}_{xy}},{{d}_{yz}}\]    

    Correct Answer: A

    Solution :

     Only those d orbitals whose lobes are directed along X-, Y- and Z-directions hybridise with s and p orbitals. In other three d orbitals namely\[{{d}_{xy}},{{d}_{yz}}\]and\[{{d}_{xz}},\]the extent of their overlap with s and p orbitals is much lesser than \[{{d}_{{{x}^{2}}-{{y}^{2}}}}\]and \[{{d}_{{{z}^{2}}}}\]orbitals.
