Chemistry - Coordination Chemistry Question with Solution | TestHub
Examine the following statements regarding chelating ligands and their biomedical applications :
(1) -Nitroso- -naphthol acts as a chelating ligand.
(2)Vitamin B12, cyanocobalamine, the anti-pernicious anaemia factor, is a coordination compound of cobalt.
(3) Desferrioxamine-B is employed in the treatment of Wilson's disease (copper overlaod)
(4) D-Penicillamine functions as a chelating agent used in the treatment of iron toxicity.
Select the correct truth scheme (T = True , F = False)
Options:
Answer:
Solution:
Statements (1) and (2) are true because -nitroso--naphthol is a known chelating ligand, and Vitamin B₁₂ is a coordination complex containing cobalt.
Statement (3) is false because Desferrioxamine-B is used to treat iron toxicity, not copper overload (Wilson's disease).
Statement (4) is false because D-Penicillamine is used to treat copper overload (Wilson's disease), not iron toxicity.
Therefore, the correct truth value sequence is TTFF, making (D) the correct option.
