Ethylene diaminetetraacetate (EDTA) ion is :

  1. Tridentate ligand with three "N" donor atoms
  2. Hexadentate ligand with four "O" and two "N" donor atoms
  3. Unidentate ligand
  4. Bidentate ligand with two "N" donor atoms

Answer

(2) Hexadentate ligand with four "O" and two "N" donor atoms

Solution

As per NCERT, EDTA4- (ethylenediaminetetraacetate ion) binds a metal ion through two N atoms of the ethylenediamine part and four O atoms of the four acetate groups.

∴ it is a hexadentate ligand with four O and two N donor atoms.

Answer: (2)
