Which atoms from EDTA are used to bind to metal ions during formation of complex?
Options
- AFour nitrogen and two oxygen atoms
- BThree nitrogen and three oxygen atoms
- CFour oxygen and two nitrogen atoms
- DThree oxygen, two nitrogen and one magnesium atoms
Correct answer
C. Four oxygen and two nitrogen atoms
Step-by-step solution
EDTA (Ethylenediaminetetraacetate) is a hexadentate ligand.
Its chemical structure contains two nitrogen atoms and four carboxylate groups.
During the formation of a complex with a metal ion, it donates electron pairs from the two nitrogen atoms and the four oxygen atoms of the carboxylate groups.
Thus, four oxygen and two nitrogen atoms are used to bind to metal ions.
Answer: Four oxygen and two nitrogen atoms
Its chemical structure contains two nitrogen atoms and four carboxylate groups.
During the formation of a complex with a metal ion, it donates electron pairs from the two nitrogen atoms and the four oxygen atoms of the carboxylate groups.
Thus, four oxygen and two nitrogen atoms are used to bind to metal ions.
