Olefins
In chemistry, an alkene is a hydrocarbon that contains a carbon–carbon double bond.The term is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds. However, the IUPAC recommends using the name "alkene" only for acyclic hydrocarbons with just one double bond; alkadiene, alkatriene, etc., or polyene for acyclic hydrocarbons with two or more double bonds; cycloalkene, cycloalkadiene, etc. for cyclic ones; and "olefin" for the general class — cyclic or acyclic, with one or more double bonds.Acyclic alkenes, with only one double bond and no other functional groups (also known as mono-enes) form …
