Why ozone cracking of rubber occurs is to be explained. Concept introduction: Alkenes react with ozone in a reaction called ozonolysis. The C=C bond of the alkene is broken and the two carbons are oxidized to carbonyl groups. The reaction starts with a [4 + 2] cycloaddition of ozone across the π bond to form a cyclic compound called molozonide that contains a − O − O − O − bridge between the two carbons. This is followed by a rearrangement via a [4 + 2] cyclo elimination and [4 + 2] cycloaddition to an ozonide. In the ozonide, the carbons of the initial double bond are doubly bridged, by − O − O − and − O − . The final reduction step converts the unstable ozonide to two carbonyl groups.
