Question

The reaction representing the Mond process for metal refining is ______ [

Select the correct option:

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

$2 \mathrm{~K}\left[\mathrm{Au}(\mathrm{CN})_2\right]+\mathrm{Zn} \xrightarrow{\Delta} \mathrm{K}_2\left[\mathrm{Zn}(\mathrm{CN})_4\right]+2 \mathrm{Au}$

$\mathrm{Zr}+2 \mathrm{I}_2 \xrightarrow{\Delta} \mathrm{Zr} \mathrm{I}_4 \mid$

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

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Mond's process uses: $\mathrm{Ni}+4 \mathrm{CO} \rightarrow\left[\mathrm{Ni}(\mathrm{CO})_4\right]$
