WebH2O is undoubtedly a weak field ligand. However while dealing with complexes having central atom in higher oxidation state or of 2nd and 3rd transition series the nuclear pull of the central atom changes the scenario. In simple words it can be said that H2O behaves as a strong field ligand with Co+3 and ions of 2nd and 3rd transition series. WebApr 5, 2024 · Generally, higher the electronegativity, weaker is the ligand i.e. if a ligand uses its oxygen atom to bind with the central metal atom, it is termed as a weak field ligand and if the ligand uses its carbon, or nitrogen atom for binding with the central metal atom, it is termed as a strong field ligand.
