Which of the following is not the drawback of Valence bond theory of coordination compounds?

Geometry of the complex can be decide only on the basis of observed magnetic nature of the complex It does not give any idea about the nature of the ligands. Thermodynamic stability cannot be determined Each ligand should have at least one lone pair of electrons.

Each ligand should have at least one lone pair of electrons.

Each ligand should have at least one lone pair of electrons: This is one of the postulates of Valence bond theory of Co-ordination compounds.
