Ethylene diaminetetraacetate (EDTA) ion is:
1. | Bidentate ligand with two "N" donor atoms |
2. | Tridentate ligand with three "N" donor atoms |
3. | Hexadentate ligand with four "O" and two "N'' donor atoms |
4. | Unidentate ligand |
The correct order of increasing field strength of ligands is:
1.
2.
3.
4.
