Question

Which of the following compounds does not undergo a haloform reaction?

Options

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

• \[\begin{array}{cc}
  \ce{CH3 - C - CH3}\\
  ||\\
  \ce{O}
  \end{array}\]

• \[\begin{array}{cc}
  \ce{C2H5 - CH - C2H5}\\
  |\phantom{..}\\
  \ce{OH}
  \end{array}\]

• \[\begin{array}{cc}
  \ce{CH3 - C - C2H5}\\
  ||\phantom{.}\\
  \ce{O}\phantom{.}
  \end{array}\]

Answer 1

\[\begin{array}{cc}
\ce{C2H5 - CH - C2H5}\\
|\phantom{..}\\
\ce{OH}
\end{array}\]

Explanation:

Because haloform is produced by a compound that contains \[\begin{array}{cc}\phantom{.....}\ce{O}\\\phantom{.....}||\\\ce{CH3 - C -}\end{array}\] group or \[\begin{array}{cc}\ce{R - CH - CH3}\\|\phantom{.....}\\\ce{OH}\phantom{...}\end{array}\] only.
