Expert Answer:

The VB theory, to a number of assumptions.

(i) It does not give quantitative interpretation of magnetic data.

(ii) It does not explain the colour exhibited by coordination compounds.

(iii) It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.

(iv) It does not make exact predictions regarding the tetrahedral and square planar structures of 4-coordinate complexes.

(v) It does not distinguish between weak and strong ligands.
