Question

on the basis of CFT write the electronic configuration of D6 in terms of t2g and EG in an octahedral field when delo is lesser than p

Answer 1

Explanation:

Electronic Configuration w.r.t. CFT of octahedral species :

The electron configuration is t⁴₂g, e²g.

It is normally achieved after splitting of the d- orbital for octahedral species.

if Δ0 < P, then the complex is a high spin complex formed by the association of weak field ligand with metallic ion.  

Then, the 4th electron will enter in the $e_{g}$ orbital and the electronic configuration will be:

$t^{3}_{2}g  e^{3}_{g}$
