	Column I		Column II
(A)	Impure metal to volatile complex	(i)	Blistered copper
(B)	$2CuO+C{u}_{2}S\to 4Cu+S{O}_2$	(ii)	Mond process
(C)	Purification of mercury	(iii)	Van Arkel process
(D)	Purification of zirconium	(iv)	Liquation

• A. (A) $\to$(iv), (B)$\to$(iii), (C)$\to$(i), (D) $\to$ (ii)
• B. (A) $\to$(ii), (B)$\to$(i), (C)$\to$(iv), (D) $\to$ (iii)
• C. (A) $\to$(i), (B)$\to$(ii), (C)$\to$(iv), (D) $\to$ (iii)
• D. (A) $\to$(iii), (B)$\to$(iv), (C)$\to$(i), (D) $\to$ (ii)

Answer 1

The correct option is B (A) $\to$(ii), (B)$\to$(i), (C)$\to$(iv), (D) $\to$ (iii)

A. In Mond's process, molten metal changes to volatile complex.

Impure $Ni+4CO\stackrel{330K}{\to }Ni{\left(CO\right)}_4$ [Volatile complex]

B. Blisters are obtained in this. So, it is called Blister Copper.

C. Mercury is purified either by liquidation or by distillation as both works on same principle.

D. Van-Arkel process is for Zirconium refining.
