Ozonolysis – when followed by reduction, yields carbonyl compounds by cleavage of the double bond 9. Radical Chain Additions To Alkenes – • Chain carrier adds to the π bond to form the more highly substituted radical • Allows for anti-Markovnikov hydrobromination of alkenes • Allows for the addition of thiols and some halomethanes 10. Polymers – Alkenes react with themselves to form polymers. • Initiation by charged species, radicals or some transition metals
