which compound is classified as a hydrocarbon
Ethane, C2H6, is an alkane and is an example of a saturated hydrocarbon. Ethene, C2H4, is an alkene and is an example of unsaturated hydrocarbon. Ethyne, C2H2, is an alkyne and is also an example of unsaturated hydrocarbon. Aromatic compounds are unsaturated hydrocarbons and contain a benzene ring.wo different organic compounds can also have the same number of carbon atoms. These are called isomers. Isomers are molecules that have the same molecular formulas but different structures and thus different physical and chemical characteristics. An example of isomerism is butane and 2-methylpropane.
