Answer:
(iii) [Fe(C2O4)3]3−
Explanation:
Chelation is a form of metal ion bonding between ions and molecules. It involves the formation or presence between a polydentate ligand and a single central atom of two or more separate coordinate bonds. These ligands are called chelants, chelators, agents of chelation, or agents of sequestration.
The stability of a complex always increases by chelation. Therefore, the most stable complex is [Fe(C2O4)3]3−
