WebAlkenes are hydrocarbons which contain a carbon-carbon double bond. Why crack hydrocarbons? There are two problems with the output from fractional distillation: The … WebFractional Distillation produces many different parts (or fractions) each with different boiling points, Distillation only separates the volatile and nonvolatile products. Cracking: Cracking is the process of breaking a long Hydrocarbon chain into shorter Hydrocarbon chains, some of which can be Alkenes.
