Alkene Introduction: also called olefins, and alkyne belong to the class of unsaturated aliphatic hydrocarbons. Alkenes form a homologous series, the alkenes with general formula CnH2n. The alkenes is one of three homologous series that contain carbon-carbon double bonds; the other two being the alkynes and the arenes. Alkenes are relatively stable compounds, but are more reactive than alkanes. Polymerization of alkenes is an economically important reaction which yields polymers of high industrial value, such as the plastics polyethylene and polypropylene.

Many of the alkenes have common names, e.g., ethene is called ethylene and propene propylene. The alkenes as a group are sometimes called the ethylene series. Many of the reactions in which alkenes take part involve the cleavage of half the carbon-carbon double bond and subsequent formation of two single bonds, one to each of the adjacent carbon atoms. Such reactions include hydrogenation, with the formation of an alkane, and hydration, with the formation of an alcohol.

The most common industrial synthesis path for alkenes is cracking of petroleum. Alkenes can be synthesized from alcohols via an elimination reaction that removes one water molecule. Catalytic synthesis of higher α-alkenes can be achieved by a reaction of ethene with triethylaluminium, an organometallic compound in the presence of nickel, cobalt or platinum.
