Question

Which of the following is hexadentate ligand?

• A. Ethylene diamine
• B. Ethylene diamine tetra acetic acid
• C. 1, 10-phenanthroline
• D. Acetyl acetonate

Hint:

EDTA is a hexadentate ligand that forms strong complexes with metal ions due to its six donor atoms.

Answer 1

The Correct Option is B

Step 1: Identifying hexadentate ligand.
A hexadentate ligand is one that can donate six pairs of electrons to a metal ion. Ethylene diamine tetra acetic acid (EDTA) is a well-known hexadentate ligand as it has six donor atoms.

Step 2: Conclusion.
Thus, the correct answer is option (B).

Final Answer: \[ \boxed{\text{(B) Ethylene diamine tetra acetic acid}} \]
