Classified as: Cracking, Thermal
Thermal cracking involves breaking longer alkanes into a mixture of shorter alkanes (including branched alkanes) and the olefins: ethene and propene.
The mechanism involves radical cleavage and then radical beta-eliminateion of ethene or propene, the reverse of radical polymerisation.
