Question

Identify the compounds A and B in the given reaction:

\[\ce{C2H5OH ->[Cu][\Delta] A ->[CH3COCl][anhy. AlCl3] B}\]

Answer 1

\[\begin{array}{cc}
\phantom{.........................................................}\ce{OH}\phantom{................}\ce{O}\\

\phantom{.........................................................}|\phantom{...................}||\\
\ce{\underset{Ethyl alcohol}{C2H5OH} ->[Cu][\Delta] \underset{Ethanal (A)}{CH3CHO} ->[dil. NaOH] \underset{(B)}{\underset{\beta-hydroxy butyaldehyde}{H3C - CH - CH2 - C - H}}}\\
\end{array}\]
