Ethane, C2H6, is an example of a saturated hydrocarbon. Other examples of saturated compounds are octane, C8H18, and diethyl ether, C4H10O. The term unsaturated is used to designate a compound which contains double or triple bonds and therefore not every carbon is bonded to a different atom.n alkene is a hydrocarbon containing double bonds. The general formula of an alkene is CnH2n. An alkyne is a hydrocarbon containing triple bonds. The general formula of an alkyne is CnH2n-2.
