Question

The set which does not have ambidentate ligands (labeled as (i)) is:

• A. CO\(_3^{2-}\), NO\(_3^{-}\), NCS\(^-\)
• B. EDTA\(^-\), NCS\(^-\), CO\(_2^{2-}\)
• C. NO\(^-\), CO\(_3^{2-}\), EDTA\(^-\)
• D. CO\(_2^{2-}\), ethylene diamine, H\(_2\)O

Hint:

Ambidentate ligands are characterized by their ability to bind metal centers through different atoms within the same ligand.

Answer 1

The Correct Option is D

- Ambidentate ligands are ligands that can coordinate through two different donor atoms, such as NO\(_3^{-}\) and NCS\(^-\).
- CO\(_3^{2-}\), NO\(_3^{-}\), and NCS\(^-\) can act as ambidentate ligands, but CO\(_2^{2-}\) and ethylene diamine do not.
- Hence, the correct set that does not have ambidentate ligands is (4).
Thus, the correct answer is (4), CO\(_2^{2-}\), ethylene diamine, H\(_2\)O.
