The ozonolysis of an olefin gives propanone. The olefin is:
Correct answer: D. 2,3-dimethyl but-2-ene
- A. propene
- B. but-1-ene
- C. but-2-ene
- D. 2,3-dimethyl but-2-ene
Explanation
Terminal double bond on ozonolysis will produce only aldehyde. To form ketone it should not be a terminal alkene. Olefin forms only one ketone so it is a symmetrical alkene.

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.
