alleryIn Crystal Field Theory, the 5 d-orbitals in an OCTAHEDRAL field split into:
AThree lower eg + two higher t2g levels
BThree lower t2g + two higher eg levels
CAll five d-orbitals at the same energy
DTwo lower t2g + three higher eg levels
Answer & Solution
Correct answer: B. Three lower t2g + two higher eg levels
**Octahedral CFT splitting:** t2g (3 orbitals: dxy, dyz, dxz) at LOWER energy + eg (2 orbitals: dx²-y², dz²) at HIGHER energy.
Energy gap = Δ₀ (crystal field splitting).
In tetrahedral, splitting is reversed.
