NEET Chemistry Crystal Field Theory MCQ Question
The magnitude of CFSE (crystal field splitting energy, Δ₀) can be related to the configuration of d-orbitals in a coordination entity as
if Δ₀ < P, the configuration is t₂g³e₁g² = weak field ligand and high spin complex
if Δ₀ > P, the configuration is t₂g²e₁g³ = strong field ligand and low spin complex
if Δ₀ > P, the configuration is t₂g⁴e₀g = strong field ligand and high spin complex
if Δ₀ = P, the configuration is t₂g⁴e₀g = strong field ligand and high spin complex
Correct Answer
Detailed Explanation
When Δ₀ > P, electrons pair up in the lower energy t₂g orbitals, leading to a low spin configuration.
