प्रश्न
Explain the difference between a weak field ligand and a strong field ligand.
उत्तर
| Sr. No. | Weak field ligand | Strong field ligand |
| 1. | Those ligands whose crystal field splitting energy (CFSE), Δ0 has a low value are called weak field ligands. | Those ligands whose crystal field splitting energy, Δ0 has a high value are called strong field ligands. |
| 2. | Due to weak field ligands, there is no pairing of electrons and they form high-spin complexes. | Due to strong field ligands, there is pairing of electrons and they form low-spin complexes. |
