Which type of ligand is EDTA?
- A Monodentate
- B Hexadentate
- C Bidentate
- D Tridentate
Answer & Solution
Correct Answer
(B) Hexadentate
Step-by-step Solution
Detailed explanation
EDTA stands for Ethylenediaminetetraacetate ion. It has the chemical formula \((OOCCH_2)_2NCH_2CH_2N(CH_2COO)_2^{4-}\). The structure contains four oxygen atoms from the carboxylate groups and two nitrogen atoms from the amine groups that can act as donor sites. Since it has six…
