Question

Identify the compounds [A], [B], [C] and [D] in the following reaction:

\[\ce{CH3COOH + PCl5 -> [A] ->[H2][\underset{Boiling Xylene}{Pd/BaSO4}] [B] ->[K2Cr2O7 + H2SO4][{[O]}] [C] ->[Ca(OH)2, heat] [D]}\]

Answer 1

\[\begin{array}{cc}
\phantom{....}\ce{O}\\
\phantom{....}||\\
\ce{CH3COOH + PCl5 -> \underset{(A)}{\underset{Acetyle Chloride}{CH3COCl}} + POCl3 + HCl ->[Pd-BaSO4, H2][Boiling xylene] \underset{(B)}{\underset{Acetaldehyde}{H3C - C - H}} + HCl ->[K2Cr2O7 + H2SO4][{[O]}] \underset{(C)}{\underset{Acetic acid}{CH3COOH}} ->[Ca(OH)2, heat] \underset{(D)}{\underset{Acetone}{CH3COCH3}} + CO2}\\
\end{array}\]
