Question

In the following reaction, product P is:

\[\begin{array}{cc}
\phantom{....................}\ce{\underset{}{R - C - Cl} ->[H2][ Pd.BaSO4] \underset{}{P}}\\\phantom{}||\\\phantom{}\ce{O}\\
\end{array}\]

Options

• RCH₂OН

• RCOОН

• RCHO

• RCH₃

Answer 1

RCHO

Explanation:

\[\begin{array}{cc}
\phantom{...................................}\ce{O}\\
\phantom{...................................}||\\
\ce{R - C - Cl->[H2,Pd-BaSO4][Rosenmund's reaction] \underset{(product.P)}{R - C - H} + HCl}\\
||\phantom{........................................................}\\
\ce{O}\phantom{........................................................}
\end{array}\]
