Question

Which of the following does not represent a correct application of the coordination compound?

• A. cis-platin effectively inhibit the growth of tumours
• B. chlorophyll helps in photosynthesis
• C. desferrioxime B is used in treatment of lead poisoning
• D. cyanocobalamine, antipernicious anemia factor is a coordination compound of Co

Hint:

Coordination compounds have wide applications, especially in medicine (e.g., cis-platin) and environmental cleanup (e.g., desferrioxime B).

Answer 1

The Correct Option is B

Step 1: Understanding Coordination Compounds.
Coordination compounds are molecules or ions containing a central metal atom or ion bonded to surrounding ligands. These compounds have important applications in various fields such as medicine, industry, and biological systems.
Step 2: Evaluation of the options.
- Option 1: cis-platin effectively inhibits the growth of tumours. This is a well-known application of a coordination compound, where platinum complexes are used in chemotherapy.
- Option 2: Chlorophyll helps in photosynthesis. Chlorophyll is indeed involved in photosynthesis, but it is not considered a typical coordination compound. It is a complex, but its role is different from the specific application of coordination compounds.
- Option 3: Desferrioxime B is used in the treatment of lead poisoning. This is a valid application of a coordination compound, as it helps in chelation therapy for lead poisoning.
- Option 4: Cyanocobalamine, antipernicious anemia factor, is a coordination compound of Co.
Cyanocobalamine is a vitamin B₁₂ molecule, a coordination compound involving cobalt, used to treat pernicious anemia.
Step 3: Conclusion.
The only incorrect application of a coordination compound is option (2), as chlorophyll does not function as a coordination compound in photosynthesis.
Final Answer: \[ \boxed{\text{The correct answer is (2) chlorophyll helps in photosynthesis.}} \]
