When a chelating ligand replaces several monodentate ligands, the result is an increase in the number of free molecules in the system, meaning a relatively large increase in entropy. This is the major energetic factor driving the chelate effect.
Why chelate effect is called an entropy effect?
When a chelating ligand replaces several monodentate ligands, the result is an increase in the number of free molecules in the system, meaning a relatively large increase in entropy. This is the major energetic factor driving the chelate effect.
What is the effect of chelate effect?
The chelate effect explains the enhanced affinity of chelating ligands for central metal ion or atom compared to the affinity of nonchelating monodentate ligands for the same metal. Examples: [Co(en)3]3+ is more stable than [Co(NH3)6]3+ where Ethylenediamine (en) is an example of a bidentate ligand.
