WebWhen a large hydrocarbon is cracked, a smaller alkane and alkene molecules are formed. Eg. octane and ethene from decane. Long hydrocarbon fraction is cracked into two smaller ones. The low-molecular mass alkanes formed make good fuels and are in high demand. The low-molecular mass alkenes are more reactive than alkanes due to their double bond.
