🧠 The Spectrochemical Rule
The field strength of a ligand determines how much it "splits" the -orbitals of a metal. This is summarized in the Spectrochemical Series, an experimental ranking of ligands.

🗺️ The Standard Approach
Let's analyze the ligands provided:
1. Halogens: These are typically the weakest ligands. Therefore,  should be at the lower end.
2. Pseudohalogens:  (when S-bonded) is very weak, even weaker than  according to the series.
3. Oxygen Donors:  (oxalate) is a medium-streng
