Alkenes | Preparation Methods | Properties

Alkenes are unsaturated hydrocarbons containing carbon-carbon double bond (C=C). The general formula of alkenes is CnH2n. The first member of alkenes i.e. ethylene or ethene (C2H4) reacts with chlorine to form an oily liquid. Hence, alkenes are also called olefins (olefient = oil forming).
