Question:
Which one of the following is vinyl alcohol?
Which one of the following is vinyl alcohol?
Show Hint
Vinyl alcohol is rarely found in isolation due to its instability but is important in industrial polymer applications.
Updated On: Jan 13, 2026
- But-2-en-2-ol
- Prop-2-en-1-ol
- Ethanol
- Methanol
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Vinyl alcohol (\( CH_2=CH-OH \)) is an unstable tautomer of acetaldehyde.
It is represented by the IUPAC name Prop-2-en-1-ol: \[ CH_3-CHOH-CH_2 \rightarrow CH_2=CH-OH. \]
Explanation: But-2-en-2-ol does not match the structure of vinyl alcohol. Prop-2-en-1-ol matches the structural and chemical characteristics of vinyl alcohol.

Top Questions on Chemical Kinetics
- Correct statements regarding Arrhenius equation among the following are:
Factor \(e^{-E_a/RT}\) corresponds to fraction of molecules having kinetic energy less than \(E_a\).
At a given temperature, lower the \(E_a\), faster is the reaction.
Increase in temperature by about \(10^\circ\text{C}\) doubles the rate of reaction.
Plot of \(\log k\) vs \(\dfrac{1}{T}\) gives a straight line with slope \(= -\dfrac{E_a}{R}\).
