The reaction representing the Mond process for metal refining is

[JEE Main 2023, 29 Jan (Shift 1)]

a

\(Ni +4 CO \xrightarrow{\Delta} Ni ( CO )_4\)

b

\(2\mathrm{K}\left[\mathrm{Au}{\left(\mathrm{CN}\right)}_{2}\right]+\mathrm{Zn}\overset{∆}{\to }{\mathrm{K}}_{2}\left[\mathrm{Zn}{\left(\mathrm{CN}\right)}_{4}\right]+2\mathrm{Au}\)

c

\(Zr +2 I _2 \xrightarrow{\Delta} ZrI _4\)

d

\(ZnO + C \xrightarrow{\Delta} Zn + CO\)

✓ Correct answer: a)

\(Ni +4 CO \xrightarrow{\Delta} Ni ( CO )_4\)

Explanation

Mond's process is used to refine Ni.
\[
Ni +4 CO \rightarrow\left[ Ni ( CO )_4\right]
\]
