3-dimethyl-2-butene on reaction with O3/H2O yields two molecules of:
Correct answer: B. Acetone
- A. Acetaldehyde
- B. Acetone
- C. Formaldehyde
- D. Benzaldehyde
Explanation
Acetone is formed in the ozonolysis of 3-dimethyl-2-butene. The double bond in the alkene is cleaved, and the resulting carbonyl groups form acetone upon aqueous workup.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
