Unsaturated Hydrocarbon
Contain carbon-to-carbon double or triple bonds.
An unsaturated hydrocarbon is a type of organic compound that contains one or more double or triple bonds between carbon atoms. They are also known as alkenes and alkynes, respectively.
Alkenes have the general formula CnH2n and contain at least one double bond between two carbon atoms. The double bond consists of a sigma bond and a pi bond. Some examples of alkenes include ethene (C2H4), propene (C3H6), and butene (C4H8).
Alkynes have the general formula CnH2n-2 and contain at least one triple bond between two carbon atoms. The triple bond consists of a sigma bond and two pi bonds. Some examples of alkynes include ethyne (C2H2), propyne (C3H4), and butyne (C4H6).
Unsaturated hydrocarbons are more reactive than saturated hydrocarbons because the double or triple bond provides more sites for chemical reactions to occur. They can undergo addition reactions by breaking the double or triple bond and adding new atoms or groups to the molecule. This makes them useful in various industrial processes and in the production of many different types of chemicals.
