Cyclohexene is treated with acidified KMnO4 solution followed by heating. Identify the organic product formed.
- Picric acid
- Oxalic acid
- Acetic acid
- Adipic acid
Correct answer: Adipic acid
Solution
Hot concentrated acidic KMnO4 oxidatively cleaves the double bond in cyclohexene. Since the double bond is inside a six-membered ring, both carbons of the double bond are converted to -COOH groups but remain connected by the rest of the ring chain, yielding hexanedioic acid (adipic acid), a six-carbon dicarboxylic acid.
