MCQ
Which of the following is not chelating agent?
- ✓thiosulphato
- Boxalato
- Cglycinato
- Dethylene diamine
✓
Answer
Correct option: A.
thiosulphato
a
Oxalato, glycinato and ethylene diamine are large ligands and they can form rings because they all are bidentate ligands. So, they all are also chelating ligands. Thiosulphato is a monodentate ligand and hence, cannot form chelate rings. So, it is not a chelating ligand.
