Ethene, C2H4, is an example of an unsaturated hydrocarbon. Other examples of unsaturated compounds are benzene, C6H6, and acetic acid, C2H4O2. All bond angles about the carbon-carbon double bond are 120o. All atoms bonded to the double bonded carbon atoms lie in the same plane.n unsaturated hydrocarbon is a hydrocarbon containing at least one double or triple bond. An 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.
See also: Saturation (chemistry). In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds. Alkanes are an example of saturated compounds.An unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively. Saturated and unsaturated compounds need not consist only of a carbon atom chain.They can form straight chain, branched chain, or ring arrangements. They can have functional groups, as well. It is in this sense that fatty acids are classified as saturated or unsaturated.aturated and unsaturated compounds need not consist only of a carbon atom chain.
