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.
