Question

A cyclic multidentate ligand increases the stability of the complex.
If true 1 else 0.

• A. 1

Answer 1

The correct option is A 1
A straight chain multidentate ligand is useful as well as the cyclic multidentate ligand, but it has been found that the stability of the complex increases in the case of using the cyclic ligand as compared to the straight chain ligand. This may be attributed to the electrostatic and stearic repulsion between the donor atoms at both ends and the disadvantageous change of entropy though the straight chain multidentate ligand is superior to the monodentate ligand in trapping of a cation.
