WebNov 14, 2024 · NH3 is a ligand with medium field strength. In case of H2O, it is weaker ligand as compared to NH3 as the donor atom is Oxygen which is more electronegative than Nitrogen. So as the electronegativity of central atom decrease, the ligand becomes stronger. so in NH3, pairing will occur and in H2O pairing will not occur. 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.
