Which of the following is allylic alcohol?
- A But-1-en-1-ol
- B But-3-en-1-ol
- C But-2-en-1-ol
- D Butane-1,3-diol
Answer & Solution
Correct Answer
(C) But-2-en-1-ol
Step-by-step Solution
Detailed explanation
The alcohol where -OH group is attached to the saturated C beside \(\mathrm{C}=\mathrm{C}\) group, is an allylic alcohol.
\(\begin{gathered}\mathrm{HO}-\stackrel{1}{\mathrm{C}} \mathrm{H}_2-\stackrel{2}{\mathrm{C}} \mathrm{H}=\stackrel{3}{\mathrm{C}} \mathrm{H}-\stackrel{4}{\mathrm{C}} \mathrm{H}_3 \\ \text { But-2-en-l-ol }\end{gathered}\)
\(\begin{gathered}\mathrm{HO}-\stackrel{1}{\mathrm{C}} \mathrm{H}_2-\stackrel{2}{\mathrm{C}} \mathrm{H}=\stackrel{3}{\mathrm{C}} \mathrm{H}-\stackrel{4}{\mathrm{C}} \mathrm{H}_3 \\ \text { But-2-en-l-ol }\end{gathered}\)
