Alkenes are unsaturated hydrocarbons

Alkenes are unsaturated hydrocarbons

Alkenes are hydrocarbons containing a carbon-carbon double bond, written C=C\text{C}=\text{C}C=C. A carbon-carbon double bond consists of two covalent bonds joining the same two carbon atoms. For example, propene has the structural formula CH3CH=CH2\text{CH}_3\text{CH}=\text{CH}_2CH3​CH=CH2​, while propane has the structural formula CH3CH2CH3\text{CH}_3\text{CH}_2\text{CH}_3CH3​CH2​CH3​.
