Question

The degeneracy of d-orbitals is lost under:
(I) Strong field ligand (II) Weak field ligand (III) Mixed field ligand (IV) Chelated ligand field
Choose the correct code.

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

Answer 1

The correct option is C I, II, III and IV

When the ligands approach the metal ion, the degeneracy of d-orbitals is lost. This is irrespective of the strength of the ligand field.
Thus, ligand field created by strong, weak, mixed or chelating ligands cause the loss of the degeneracy of d-orbitals.
