III. VBT does not distinguish between weak field ligand and strong field ligand.

• A. I, II, III
• B. I, II
• C. II, III
• D. I, III

Answer 1

The correct option is D I, III

Limitations of Valence Bond Theory
It involves a number of assumptions.​
It does not explains the colour exhibited by co-ordination compounds.
It does not explain and gives quantitative interpretation of magnetic data.
It does not distinguish between weak field ligand and strong field ligand.
It does not explain the colour exhibited by the coordination compounds.​
It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.​
It does not make exact predictions regarding the tetrahedral and square planar structures of ​4-coordinate complexes.​
