Cyclohexene on oxidation by KMnO ₄ in dilute H ₂ SO ₄ produces
Options
- Abenzene-1,4-dicarboxylic acid
- Bpent-2-enoic acid
- Chexane-1,6-dioic acid
- Dbenzene-1,2-dicarboxylic acid
Correct answer
C. hexane-1,6-dioic acid
Step-by-step solution
Cyclohexene is a cyclic alkene containing a six-membered ring with one double bond. When treated with a strong oxidizing agent like KMnO ₄ in an acidic medium (dilute H ₂ SO ₄ ), the carbon-carbon double bond undergoes oxidative cleavage. The ring opens up, and the two vinylic carbon atoms are fully oxidized to carboxylic acid groups. Since cyclohexene contains six carbon atoms, the resulting product is a straight-chain dicarboxylic acid with six carbon atoms. The product is HOOC -( CH ₂)₄- COOH , which is hexane-1
