Question

Identify the tetradentate ligand from the following.

• A. Ethylene diamine tetracetato
• B. Triethylene tetramine
• C. Dimethyl glyoximato
• D. Oxalato

Hint:

Tetradentate ligands are capable of coordinating with a metal center using four donor atoms. These ligands typically have high stability constants due to the formation of multiple bonds.

Answer 1

The Correct Option is B

Step 1: Understanding tetradentate ligands.
A tetradentate ligand is a ligand that can form four bonds with a metal center. Triethylene tetramine is a common tetradentate ligand that can coordinate with metal centers through four nitrogen atoms.

Step 2: Analyzing the options.
(A) Ethylene diamine tetracetato: This ligand is bidentate, meaning it can form two bonds, not four.
(B) Triethylene tetramine: This is the correct answer as it is a tetradentate ligand.
(C) Dimethyl glyoximato: This is a bidentate ligand, not tetradentate.
(D) Oxalato: This is also a bidentate ligand, not tetradentate.

Step 3: Conclusion.
The correct answer is (B) Triethylene tetramine.
