The catalyst used in Rosenmund reaction is

A
$\mathrm{Zn} / \mathrm{Hg}$
Correct answer
B
$\mathrm{Pd} / \mathrm{BaSO}_{4}$
C
Raney Ni
D
Na in Ethanol

Solution

Roseumund's reaction - $\mathrm{RCOCl}+\mathrm{H}_{2} \stackrel{\mathrm{Pd} / \mathrm{BaSO}_{4}}{\longrightarrow} \mathrm{RCHO}+\mathrm{HCl}$

Hence, the correct answer is option: 'B'.
