Question

Which of the following metals is refined by vapour phase refining in Mond process?

• A. Zn
• B. Si
• C. Ni
• D. Zr

Hint:

The Mond process is used specifically for purifying nickel by converting it into a volatile carbonyl complex.

Answer 1

The Correct Option is C

Step 1: Understanding the Mond process.
The Mond process is a method used to purify nickel by converting it into a volatile carbonyl complex and then decomposing it to obtain pure nickel. This process is specifically used for nickel.

Step 2: Analyzing the options.
(A) Zn: Zinc is not purified by the Mond process.
(B) Si: Silicon is not refined by the Mond process.
(C) Ni: Correct — Nickel is refined by the Mond process.
(D) Zr: Zirconium is not refined by the Mond process.

Step 3: Conclusion.
The correct answer is (C) Ni, as nickel is refined using the Mond process.
