What are the factors affecting the chelate effect?
The factors which contribute to the chelate, macrocyclic and cryptate effects are described.
These include the dilution effect, translational entropy, intrinsic basicities of donor atoms, coulombic attractions and repulsions of charged ions and groups, and covalent character of the coordinate bonds.
The macrocyclic effect follows the same principle as the chelate effect, but the effect is further enhanced by the cyclic conformation of the ligand.
Macrocyclic ligands are not only multi-dentate, but because they are covalently constrained to their cyclic form, they allow less conformational freedom._{27 sept. 2021}

What is the origin of chelation?

Chelation has its origin in the Greek word chele that means claw of a lobster, thus depicting the concept of clinging or holding with a strong grip.
The term chelate was first applied by Sir Gilbert T.
Morgan and H.
D.
K.
Drew in 1920.

What is the role of thermodynamics data in the formation of chelation?

Thermodynamic data shows that a favorable increase in entropy often makes a significant contribution to the stability of a chelate.
In addition the environment, for example, the pH, plays an important role in chelation reactions.

The chelate effect is the greater affinity of chelating ligands for a metal ion than that of similar nonchelating (monodentate) ligands for the same metal. The thermodynamic principles underpinning the chelate effect are illustrated by the contrasting affinities of copper(II) for ethylenediamine (en) vs. methylamine.
