WebOzonolysis is the process by which ozone (O 3) reacts with alkenes (olefins) to break the double bond and form two carbonyl groups. If the double bond of the alkene is substituted with hydrogen or carbon atoms, the carbonyl groups that are formed are either aldehydes or ketones. Acyclic alkenes form two carbonyl compounds while cyclic alkenes ...
