Q.
Which of the following energy level diagram for $[FeF_{6}]^{3-}$ is correct on the basis of crystal field theory?
Coordination Compounds
Solution:
Option (C) represents the correct energy level diagram. Since fluoride ion is a weak field ligand, $3 d$ electrons do not pair up. Also in octahedral field, $eg$ orbitals have higher energy than $t _{2 g }$ orbitals.
