The Chelate Effect Makes Complexes More Stable

The video explains the concept of bidentate ligands, focusing on ethylene diamine and its role in the chelate effect, which increases the stability of metal complexes. It introduces EDTA, a tetradentate ligand, and its applications in biochemistry. The chelate effect is driven by entropy, making dissociation unlikely. The video also covers biological examples of chelation, such as in DNA polymerase.
