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.

Options

  1. A(I) and (II) only
  2. B(II) and (III) only
  3. C(I) and (III) only
  4. D(I), (II) and (III)

Correct answer

A. (I) and (II) only

Step-by-step solution

Valence Bond Theory cannot explain the colour of transition metal complexes .this theory was also unable to distinguish between weak and strong Fields ligands. Valence Bond Theory does not explain and give quantitative interpretation of magnetic data. Hence, statement (II) is not right.
