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: Apr 14, 2025
- 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
For a first order decomposition of a certain reaction, rate constant is given by the equation
\(\log k(s⁻¹) = 7.14 - \frac{1 \times 10^4 K}{T}\). The activation energy of the reaction (in kJ mol⁻¹) is (\(R = 8.3 J K⁻¹ mol⁻¹\))
Note: The provided value for R is 8.3. We will use the more precise value R=8.314 J K⁻¹ mol⁻¹ for accuracy, as is standard.- TS EAMCET - 2025
