Question

The correct statements among I to III are:
(I) Valence bond theory cannot explain the color exhibited by transition metal complexes.
(II) Valence bond theory can predict quantitatively the magnetic properties of transition metal complexes.
(III) Valence bond theory cannot distinguish ligands as weak and strong field ones.

• A. (I) and (II) only
• B. (I), (II) and (III)
• C. (I) and (III) only
• D. (II) and (III) only

Answer 1

The correct option is C (I) and (III) only

Solution:- (D) $I,III$

VBT does not explain the colour exhibited by co-ordination compounds.

VBT does not explains and gives quantitative interpretation of magnetic data.

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