DIFFERENCE BETWEEN VALENCE BOND THEORY AND MOLECULAR ORBITAL THEORY

 DIFFERENCE BETWEEN VALENCE BOND THEORY AND MOLECULAR ORBITAL THEORY:

•VALENCE BOND THEORY:

(1)Only Valence shell electrons are involved in bond formation.

(2) The two concerned atoms don't lose their individual identity.

(3) It doesn't explain the Para magnetic behaviour of molecules.

(4) It doesn't give idea about bond order.

(5) It doesn't explain the non existence of He2 molecule.

•MOLECULAR ORBITAL THEORY:

(1) All the electrons of interacting atoms are involved in bond formation.

(2) The two atoms lose their individual identity.

(3) It explain the Para magnetic behaviour.

(4) It give idea about bond order by which we can determine that whether the bond is single, double or triple.

(5) It explain the non existence of He2 molecule.
