Question

Jahn-Teller effect is not observed in high spin complexes of

Moderate

A

$d^{7}$
B

$d^{8}$
C

$d^{4}$
D

$d^{9}$

Solution

Jahn-Teller distortion is usually significant for asymmetrically occupied $e_{g}$ orbitals since they are directed towards the ligands and the energy gain is considerably more.
In case of unevenly occupied $t_{2 g}$ orbitals, the Jahn-Teller distortion is very weak since the $t_{2 g}$ set does not point directly at the ligands and therefore, the energy gain is much less. High spin complexes
