Splitting energy is less then pairing energy, hence it is a weak field ligand splitting. Thus t2 g orbitals are half filled then electron goes to eg orbital before pairing.

Q. If $Δ_{0} < P,$ the correct electronic configuration for $d^{4}$ system will be -

$t_{2 g}^{4} e_{g}^{0}$

$t_{2 g}^{3} e_{g}^{1}$

$t_{2 g}^{0} t_{g}^{4}$

$t_{2 g}^{2} e_{g}^{2}$

Splitting energy is less then pairing energy, hence it is a weak field ligand splitting. Thus $t_{2 g}$ orbitals are half filled then electron goes to $e_{g}$ orbital before pairing.
