The ozonolysis of an olefin gives propanone (acetone). The olefin is:
Correct answer: D. 2,3-dimethyl-2-butene
- A. propene
- B. but-1-ene
- C. but-2-ene
- D. 2,3-dimethyl-2-butene
Explanation
Ozonolysis cleaves a double bond and replaces it with two carbonyl groups. To get only one product, the starting alkene must be symmetrical. The ozonolysis of 2,3-dimethyl-2-butene produces two molecules of propanone (acetone).

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
