Question

Which of the following alkenes gives only acetic acid on oxidation with hot concentrated KMnO4.
Options
A Ethylene
B 1-Butene
C Propene
D 2-Butene
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Oxidation of 2-butene (CH3CH=CHCH3) with hot concentrated KMnO4 cleaves the double bond. Each carbon of the double bond (bearing a CH3 group) is oxidized to acetic acid (CH3COOH).

Hint

Which alkene gives only acetic acid upon oxidative cleavage?
