What is the difference between a weak field ligand and a strong field ligand?
उत्तर
| S.No. | Weak Field Ligand | Strong Field Ligand |
| 1. | These are the ligands used in octahedral complexes in which the crystal field stabilization energy Δ° is less than pairing energy (P) in a single orbital. | These are the ligands used in octahedral complexes in which the crystal field stabilization energy Δ° is greater than pairing energy (P). |
| 2. | Complexes formed by these ligands are also known as high-spin complexes. | Complexes formed by these ligands are also known as low-spin complexes |
| 3. | The complexes formed are generally paramagnetic in nature. | The complexes formed are mostly diamagnetic or comparatively less paramagnetic in nature. |
