The Valence Bond theory explains the formation, structures and magnetic behaviour of coordination compounds
Limitations of Valence bond theory
- Valence bond theory failed to explain the tetra valency exhibited by carbon.
- No insight offered on the energies of the electrons.
- The theory assumes that electrons are localized in specific areas.
- It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.
- Weak and strong ligands are not differentiated.
- The colour exhibited by coordination compounds is not explained.
