Question:
Draw figure to show the splitting of d orbitals in an octahedral crystal field.
Solution:
The splitting of the $d$ orbitals in an octahedral field takes palce in such a way that $d_{x^{2}-y^{2}}, d_{z^{2}}$ experience a rise in energy and form the $e_{g}$ level, while $d_{x y}, d_{y z}$ and $d_{z x}$ experience a fall in energy and form the $t_{2 g}$ level.
