Which of the following energy level diagram for [FeF6]3- is correct on the basis of crystal field theory? (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

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.

Q. Which of the following energy level diagram for $[F e F_{6}]^{3 -}$ is correct on the basis of crystal field theory?

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, $e g$ orbitals have higher energy than $t_{2 g}$ orbitals.
