Question

\[\ce{CH3-CH2-CHO ->[dil][alkali] Product}\]

The product in the above reaction is:

Options

• CH₃–CH₂COOH

• CH₃–CH₂–CH₂OH

• \[\begin{array}{cc}
  \ce{CH3-CH2-CH-CH2-CHO}\\
  |\phantom{...}\\
  \ce{OH}\phantom{.}
  \end{array}\]

• \[\begin{array}{cc}
  \phantom{............}\ce{CH3}\\
  \phantom{.........}|\\
  \ce{CH3-CH2-CH-CH-CHO}\\
  |\phantom{..}\\
  \ce{OH}
  \end{array}\]

Answer 1

\[\begin{array}{cc}
\phantom{............}\ce{CH3}\\
\phantom{.........}|\\
\ce{CH3-CH2-CH-CH-CHO}\\
|\phantom{..}\\
\ce{OH}
\end{array}\]

Explanation:

\[\begin{array}{cc}\\
\phantom{......................................................}\ce{CH3}\\
\phantom{...................................................}|\\
\ce{CH3-CH2-C-H + CH3-CH-CHO ->[dil][alkali] CH3-CH2-CH-CH-C-H}\\
\phantom{...........}||\phantom{.............}|\phantom{............................}||\phantom{..........}|\phantom{...}\\
\phantom{..............}\ce{O}\phantom{............}\ce{H}\phantom{...........................}\ce{OH}\phantom{........}\ce{O}\phantom{.....}
\end{array}\]

This reaction is called Aldol Reaction.
