Vedclass · Answer

(B) The Jahn-Teller effect is a geometric distortion that occurs in non-linear molecules with unsymmetrical electronic configurations in the $e_g$ or $t_{2g}$ orbitals of octahedral complexes.For high spin complexes:- $d^4$ configuration is $t_{2g}^3 e_g^1$ (unsymmetrical).- $d^7$ configuration is $t_{2g}^5 e_g^2$ (unsymmetrical).- $d^9$ configuration is $t_{2g}^6 e_g^3$ (unsymmetrical).- $d^8$ configuration is $t_{2g}^6 e_g^2$ (symmetrical).Since the $d^8$ high spin complex has a symmetrical electronic configuration,it does not show Jahn-Teller distortion.
