Cyclohexene on oxidation with KMnO ₄ in dil. H ₂ SO ₄ forms.

Step-by-step solution

The oxidation of cyclohexene with potassium permanganate ( KMnO₄ ) in dilute sulfuric acid ( H₂SO₄ ) constitutes strong oxidative cleavage of the alkene. Cyclohexene contains two - CH = moieties at its double bond; each carbon with a hydrogen oxidizes to a carboxylic acid ( - COOH). Cleavage yields a linear chain with terminal carboxylic groups: HOOC-(CH₂)₄-COOH , known as adipic acid. Analysis of options: Cyclohexanol arises from hydration; cyclohexanone from milder oxidation or ozonolysis with reduction; hexanoic
