STANDARD Chemistry Crystal Field Theory MCQ Question
Type: MCQ-conceptual-Medium-Class 12
What is the correct electronic configuration of the central atom in K₄[Fe(CN)₆] based on crystal field theory?
A
e₄t₂²
B
t₂₄e₂g
C
t₂₆e₀g
D
e₃t₂³
Correct Answer
Option C
Detailed Explanation
In K₄[Fe(CN)₆] complex, Fe is in +2 oxidation state. As CN⁻ is a strong field ligand, it causes pairing of electrons, therefore, the electronic configuration of Fe²⁺ in K₄[CN]₆ is t₂₆e₀g.
