Chemical Bonding And Molecular Structure Question 442
Question: In an octahedral structure, the pair of d orbitals involved in $ ~d^{2}sp^{3} $ hybridization is
Options:
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} $
Show Answer
Answer:
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 lobes are at an angle of $ 45{}^\circ $ from both axis, hence the extent of their overlap with s and p orbitals is much lesser than $ {d_{x^{2}-y^{2}}} $ and $ {d_{z^{2}}} $ orbitals.
