Sketch a qualitative MO diagram for [Ni(NH3)6]2+ and identify the portion of the diagram considered by crystal-field theory. Imagine the ammonia ligands were all exchanged with a ?-donor ligand. Show how the MO diagram would be impacted. How does this help explain the placement of ligands in the spectrochemical series?
