Question

What are the limitation of valence bond theory?

Answer 1

The limitations of the Valence Bond theory will be as follows;

• The whole will not explain the tetravalency of the atoms clearly.

• The theory is not appropriate to describe the electron energies.

• The assumptions that are taken in the theory about the electrons are localized with the location specification which is not clear.  

Answer 2

Hey !!

VALENCE BOND THEORY

• It fails to explain following facts about the co-ordination compounds.
• It cannot explain the detailed magnetic properties of complex compounds.
• It cannot explain the orbital absorption spectra of co-ordination compounds.
• It fails to make distinction between strong and weak ligands.
• It does not explain thermodynamic or kinetic stabilities of coordination compounds.

GOOD LUCK !!
