NEET Chemistry Crystal Field Theory MCQ Question with Solution

Weak field ligands form high spin complexes due to (where Δ₀ is crystal field splitting and P = pairing energy)

A

Δ₀ > P

B

Δ₀ < P

C

Δ₀ = P

D

Δ₀ ≠ P

Option B

Weak field ligands cause a smaller crystal field splitting (Δ₀), which is less than the pairing energy (P), leading to high spin complexes.
