Chelating ligands bind more tightly to transition metal ions than electronically similar monodentate ions beca

Question

The entropy change for complex formation is more favorable when the ligand is chelating.
The enthalpy change for complex formation is more favorable when the ligand is chelating.
The complex is less likely to be oxidized when the ligand is chelating.
A coordination number of six can be obtained with a chelating ligand, but only four-coordinate complexes are possible with monodentate ligands.

I can't find anything in my book that relates to this.

Answer 1

If one ligand goes in, and a large number of water molecules come out, then the entropy change is huge and positive.
