Question:
The reagent used for the conversion of but-2-ene to ethanol is:
The reagent used for the conversion of but-2-ene to ethanol is:
Show Hint
Ozonolysis followed by reduction converts alkenes into alcohols or aldehydes.
Updated On: Mar 10, 2025
- anhydrous CrO\(_3\)
- DIBAL-H
- PCC
- O\(_3\)/H\(_2\)O-Zn dust
- anhydrous AlCl\(_3\)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Ozonolysis of but-2-ene in the presence of water and zinc dust breaks the double bond, forming two carbonyl compounds. The further reduction of ozonolysis products gives ethanol.
- Step 1: Ozone cleaves the double bond, forming two aldehydes or ketones.
- Step 2: Reduction with Zn/H\(_2\)O converts one of the fragments into ethanol.
Thus, the correct reagent for this conversion is O\(_3\)/H\(_2\)O-Zn dust.
