Question

Which of the following does not form a chelate?

• A. EDTA
• B. Oxalate
• C. Pyridine
• D. Ethylenediamine

Hint:

Chelating agents like EDTA form multiple bonds with a metal ion, helping to stabilize it in solution.

Answer 1

The Correct Option is C

A metal ion binding to a ligand at multiple sites results in chelate formation. Examples of ligands that form chelates include EDTA, oxalate, and ethylenediamine. Pyridine does not form chelates.
