    In the following reaction, \[C{{H}_{3}}COCl\frac{BaS{{O}_{4}}}{Pd/{{H}_{2}}}X\] Identify X out of the following

    A)  acetaidehyde 

    B)  propionaldehyde

    C)  acetone       

    D)  acetic anhydride

    Correct Answer: A

    Solution :

     \[\underset{\text{acetylchloride}}{\mathop{C{{H}_{3}}-COCl}}\,+{{H}_{2}}\xrightarrow{Pd,BaS{{O}_{4}}}\underset{\text{acetaldehyde}}{\mathop{C{{H}_{3}}CHO}}\,\] \[+\,HCl\] This reaction is called Rosenmund?s reaction.
