Question

In the following reaction,
$C{H}_{3}COCl\underset{Pd/H_2}{\stackrel{BaS{O}_4}{\to }}X$
Identify $X$ out of the following

• A. Acetaldehyde
• B. Propionaldehyde
• C. Acetone
• D. Acetic anhydride

Answer 1

Answer: (A)

$\underset{\text{acetyl}\text{chloride}}{{\text{CH}}_{\text{3}}-\text{COCl}}\text{+}{\text{H}}_{\text{2}}\stackrel{{\text{Pd-BaSO}}_{\text{4}}}{\to }\underset{\text{acetaldehyde}}{{\text{CH}}_{\text{3}}\text{CHO}}\text{+}\text{HCl}$
This reaction is called Rosenmund's reaction.
