Which one of the following is an ambidentate ligand?
Show Hint
Common ambidentate ligands: \(NO_2^-\), \(CN^-\), \(SCN^-\).
Updated On: Apr 29, 2026
- \(Cl^-\)
- \(H_2O\)
- \(H_2NCH_2CH_2NH_2\)
- \(SCN^-\)
- \(C_2O_4^{2-}\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Ambidentate ligands can coordinate through two different donor atoms, but only one at a time.
Step 1: Check \(SCN^-\).
Thiocyanate ion can bind through: \[ S \quad \text{or} \quad N \]
Step 2: Identify ambidentate nature.
Since \(SCN^-\) can attach through two possible atoms, it is ambidentate.
Step 3: Choose correct option.
Thus, the ambidentate ligand is: \[ SCN^- \]
