Chelate effect and overall stability constant (β) (Chelating ligands replace multiple monodentates: entropy gain (more particles) drives)

jee-mainjee-advancedneet-ug

Chelating ligands replace multiple monodentates — entropy gain (more particles) drives chelate effect; overall formation constant is product of stepwise K

When to use this

Ring formation 5- or 6-membered with metal is especially stable; ΔS > 0 main driver alongside ΔH.
