Question
A metal ion $M^{n+}$ having valence $d^4$ electronic configuration combines with three bidentate ligands to form a complex compound. Assuming $\triangle_{0} > \text{P}$:
Explain orbital splitting during this complex formation.

Answer

As$\triangle_{0} > \text{P}$ pairing will occur in the $\text{t}_\text{2g}$orbitals and eg orbitals will remain vacant.
