उत्तर
On the basis of crystal field theory, for a d4 ion, if Δ0 < P, then the complex is a high spin complex formed by the association of weak field ligands with the metal ion. As a result, the fourth electron enters one of the eg orbitals, thereby, exhibiting the electronic configuration \[\ce{t_2g ^3eg^1}\].
