Alkenes
Introduction
Alkenes
are hydrocarbons that contain at least one carbon-carbon double bond. They
follow the general formula CnH2n. A
double bond makes them unsaturated and more reactive than alkanes.
Olefins is another name for alkenes, derived from "olefiant gas" (oil-forming gas). This term historically referred to ethene () because it reacts with chlorine to form an oily liquid.
