NEETChemistryCoordination Compounds
Why are chelate complexes generally more stable than complexes with unidentate ligands?
Options
- AChelate complexes have fewer donor atoms.
- BChelate complexes have a higher coordination number.
- CChelate complexes have a lower denticity.
- DChelate complexes have a greater tendency to dissociate.
Correct answer
B. Chelate complexes have a higher coordination number.
Step-by-step solution
Chelate complexes form more stable structures due to the simultaneous binding of multiple donor atoms, leading to a higher coordination number for the metal ion.
