A volatile compound is formed by carbon monoxide and
- A Ni
- B Al
- C Cu
- D Si
Answer & Solution
Correct Answer
(A) Ni
Step-by-step Solution
Detailed explanation
The reaction between carbon monoxide and nickel is used in the Mond process for the purification of nickel. The reaction is given by: \(Ni(s) + 4CO(g) \rightarrow Ni(CO)_{4}(g)\). The product formed, nickel tetracarbonyl, \(Ni(CO)_{4}\), is a volatile compound. Answer: Ni
