- B \(\mathrm{A}=\mathrm{iv} \quad \mathrm{B}=\mathrm{i} \quad \mathrm{C}=\mathrm{iii}\)
- C \(\mathrm{A}=\mathrm{v} \quad \mathrm{B}=\mathrm{iv} \quad \mathrm{C}=\mathrm{ii}\)
- D \(\mathrm{A}=\mathrm{iii} \quad \mathrm{B}=\mathrm{ii} \quad \mathrm{C}=\mathrm{i}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{A}=\mathrm{v} \quad \mathrm{B}=\mathrm{iv} \quad \mathrm{C}=\mathrm{ii}\)
Step-by-step Solution
Detailed explanation
The coordination compound \(\mathrm{K}[\mathrm{Au}(\mathrm{CN})_2]\) (v) is used in the electroplating of gold. Therefore, A = v. D-penicillamine (iv) is a chelating agent used to treat Wilson's disease, which involves the removal of excess copper from the human body. Therefore,…
