Question

Which of the following ligands is tetradentate?

• A. A
• B. B
• C. C
• D. D

Hint:

Tetradentate ligands are capable of forming four bonds with a metal ion in a coordination complex.

Answer 1

The Correct Option is C

Step 1: Understanding tetradentate ligands.
A tetradentate ligand is one that can form four bonds with a metal ion. Both \( \text{NH}_2 \) and \( \text{N} \) can act as tetradentate ligands in certain coordination complexes.

Step 2: Conclusion.
Both \( \text{NH}_2 \) and \( \text{N} \) are tetradentate ligands, corresponding to option (3).
