Why does chelation leads to increase in entropy even though it leads to ring formation?

Chelation increases entropy despite forming rings because it involves the coordination of a metal ion with multiple ligands, which can lead to the release of solvent molecules. As these solvent molecules are displaced from the coordination sphere, the overall number of molecules in the system increases, contributing to greater disorder. Additionally, the flexibility and movement of the chelating ligands can enhance the overall configurational possibilities of the system, further increasing entropy. Thus, the net effect is an increase in randomness and disorder, despite the formation of a ring structure.
