• # 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) ${{d}_{xy}},{{d}_{yz}}$

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.
