For an octahedral complex, which of the following d-electron configuration will give maximum CFSE?

A

High spin `d^6`

B

Low spin `d^4`

C

Low spin `d^5`

D

High spin `d^7`

Text Solution

Verified by Experts

The correct Answer is:
C
Using formula `Delta_0 = - 0.4 xx n_(t_(2g)) + 0.6 xx n_(eg)`, the calculation reveals the maximum CFSE, for spin `d^5` configuration.
