Question:
Which of the following represents the correct structure of crotonyl alcohol?
Which of the following represents the correct structure of crotonyl alcohol?
Show Hint
Crotonyl alcohol is an alpha, beta-unsaturated alcohol. Remember that the alcohol group (-OH) is attached to the terminal carbon of the chain.
Updated On: Apr 12, 2025
- CH\(_2\)=CH-COOH
- CH\(_3\)-CH=CH-CHOH
- CH\(_3\)-CH=CH-COH
- CH\(_2\)=CH-CH\(_2\)-OH

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Crotonyl alcohol is an unsaturated alcohol with the structure where the alcohol group (-OH) is attached to the terminal carbon of the butene chain. The correct structure is CH\(_3\)-CH=CH-COH, where the hydroxyl group is bonded to the -CH\(_2\) group at the end of the chain, and the molecule has a conjugated system with a double bond between the second and third carbons.
- Option (A) is incorrect as it represents crotonic acid, not crotonyl alcohol.
- Option (B) is incorrect because it has the wrong functional group (hydroxyl group on the aldehyde).
- Option (D) is incorrect as it represents 3-buten-1-ol, not crotonyl alcohol. Therefore, the correct answer is option (C).
- Option (B) is incorrect because it has the wrong functional group (hydroxyl group on the aldehyde).
- Option (D) is incorrect as it represents 3-buten-1-ol, not crotonyl alcohol. Therefore, the correct answer is option (C).
