Question

Which among the following is an example of allylic alcohol?

Options

• Propane-1, 3-diol

• 2-methylbut-3-en-2-ol

• Propane-1, 2, 3-triol

• 2-phenyl propane-2-ol

Answer 1

2-methylbut-3-en-2-ol

Explanation:

An example of an allylic alcohol is 2-methylbut-3-en-2-ol. If the hydroxyl group is attached to an allylic carbon atom \[\ce{C = C}\], it is referred to as allylic alcohol.

\[\begin{array}{cc}
\ce{OH}\phantom{.....}\\
|\phantom{.......}\\
\ce{H3C - C - CH = CH3}\\
|\phantom{.......}\\
\phantom{..}\ce{\underset{\text{2-methylbut-3-en-2-ol}}{CH3}}
\end{array}\]
