Question
Identify A, B, C and D.
\[\ce{ethanoic acid ->[SOCl2] A ->[Pd/BaSO4] B ->[NaOH] C ->[][\Delta] D}\]
Solution
\[\begin{array}{cc}
\ce{\underset{(Ethanoic acid)}{CH3COOH} ->[SOCl2] \underset{\underset{(A)}{(Acetyl chloride)}}{CH3COCl} ->[Pd/BaSO4][H2] \underset{\underset{(B)}{(Acetaldehyde)}}{CH3CHO} + HCl ->[NaOH] \ce{CH3 - CH - CH2 - CHO} ->[-H2O][\Delta] \underset{\underset{(D)}{(Crotonaldehyde)}}{CH3 - CH = CH - CHO}}\\
\phantom{........................}|\\
\phantom{...........................}\ce{\underset{\underset{(C)}{(Aldol 3-hydroxy butanal)}}{OH}}
\end{array}\]
| A | CH3Cl | Acetyl chloride |
| B | CH3CHO | Acetaldehyde |
| C | \[\begin{array}{cc} \ce{CH3 - CH - CH2 - CHO}\\ |\phantom{..........}\\ \ce{OH}\phantom{.......} \end{array}\] |
