Question

A metal ion M^_n+ having d⁴valence electronic configuration with didentate ligand from a complex.Assuming ^_o >P ,what type hybridisation will Mⁿ+ ion have according to VBT

Answer 1

Mn⁺ will have d⁵s¹ valence shell electronic configuration. If P (pairing energy) is less than ∆_o then pairing of electrons will occurs. It means strong field ligands are present and pairing of electrons will occur. The electronic configuration in terms of t_2g and e_g will be t_2g⁶​. In terms of VBT we can say that three of the five d orbitals are filled. Shape of complex will be known by the number of ligands.
