Question

Describe Jahn Teller Effect.

Answer 1

Jahn teller effect is a geometric distortion of a non-linear molecular system that reduces its symetry and energy.

This type of distortion is typically observed among octahedral complexes where the two axial bonds can be shorter or longer then those of the equitorial bonds, The effect can also be observed in tetrahedral compound. The effect is dependent on the electronic state of system.
