alleryFor an octahedral d⁴ ion where Δo < P, what is the electron configuration?
At₂g³ eg¹
Bt₂g² eg²
Ct₂g⁴ eg⁰
Dt₂g¹ eg³
Answer & Solution
Correct answer: A. t₂g³ eg¹
When splitting is smaller than the pairing energy, the fourth electron avoids pairing and enters eg, giving a high spin t₂g³ eg¹ state.
