Webarrow_forward_ios. The CrF64 ion is known to have four unpaired electrons. Does the F ligand produce a strong or weak field? arrow_forward. The complex [Mn (H2O)6]2+ has five unpaired electrons, whereas [Mn (CN)6]4 has only one. Using the ligand field model, depict the electron configuration for each ion. WebMay 5, 2024 · May 4, 2024 at 17:36. 1. Instead of asking when is the ligand strong- or weak-field you should be asking whether the complex is high- or low-spin, as there are obviously more factors than the ligand. Ligand X can produce a high-spin complex with metal M whereas it might produce a low-spin complex with N.

WebWeak Field Ligand and Strong Field Ligand: Difference. Weak field ligands are partial charges from an atom in its lower energy state and strong field ligands are partial charges from an atom in its higher energy state. The difference between ligand EDA and H 2 O is that the former is a partial charge on an atom while the latter is not. WebJan 5, 2016 · They are classed as weak-field ligands because they generally generate a very low field split. An example of a halide complex would be the bright yellow $\ce{[FeCl6]^3-}$. You cannot take ligand $\ce{X}$ and call it strong or weak and thus expect it to make stable or unstable complexes. You cannot even take the same ligand … shodhana laboratories limited hyderabad https://groupe-visite.com
