Choose the coordination complex from the following that would present the least intense peaks in the UV-Vis spectrum
Accepted Answer
To determine which coordination complex would have the least intense peaks in the UV-Vis spectrum, we need to consider the following factors:
1. Ligand Field Strength: Stronger field ligands (e.g., CN-, CO) result in larger energy gaps between d-orbitals, leading to higher energy transitions and absorption in the UV region, thus less intense peaks in the visible region. Weaker field ligands (e.g., H2O, Cl-) cause smaller energy gaps, leading to lower energy transitions and absorption in the visible region, resulting in more intense peaks.
2. Metal Ion: Transition metal ions with higher oxidation states and smaller ionic radii generally lead to stronger ligand field splitting and more intense color.
3. Symmetry of the Complex: High symmetry complexes generally have less intense UV-Vis peaks.
Please provide the list of coordination complexes so I can analyze them based on these factors and help you determine the one with the least intense peaks.
