Which of the following is an ambident ligand ?
Which of the following is an ambident ligand ?
Show Hint
An ambident ligand has two different donor atoms but binds through only one at a time, like SCN-.
Updated On: Oct 1, 2026
- Ethylene diamine
- \(\text{Cl}^-\)
- EDTA
- SCN
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Use the definition:
Ambident = two different donor atoms, one used at a time.
Step 2: Test each ligand:
en: N,N both N. $\text{Cl}^-$: one donor. EDTA: uses several donors together (polydentate). SCN: S or N.
Step 3: Pick:
Option D.
Final Answer:
SCN can bind through S or N, so it is ambident. \[ \boxed{\text{(D) }\text{SCN}} \]
