Question

Which of the following alkenes on oxidation by KMnO₄ in dil H₂SO₄ forms adipic acid?

Options

• Hex-2-ene

• Hex-1-ene

• cyclohexene

• Hex-3-ene

Answer 1

cyclohexene

Explanation:

Cyclohexene on oxidation with KMnO₄ in the presence of dil. H₂SO₄ will form adipic acid, in which oxidative cleavage takes place, The double bond is broken to which oxygen atoms are going to be added forming a carboxylic acid group at each. Thus, the cyclic structure is broken forming adipic acid.
