Solution
The correct option is D Carbonyl
Nickel is purified by thermal decomposition of Nickel carbonyl compound, Ni(CO)4
First the impure nickel is heated upto a temperature of 50−60oC which led to the formation of Ni(CO)4
Impure Ni+4CO50−60oC−−−−−→Ni(CO)4250oC−−−→Ni+4CO
This process is known as Mond's Process.
Option D is correct.
