WebBy definition, alkenes are hydrocarbons with one or more carbon–carbon double bonds (R2C=CR2), while alkynes are hydrocarbons with one or more carbon-carbon triple bonds (R–C≡C–R). Collectively, they are called unsaturated hydrocarbons, which are defined as hydrocarbons having one or more multiple (double or triple) bonds between carbon atoms. Web(1) Cis-trans isomers have the same molecular formula and also the same structural formula. (2) Molecules of the compound 1,3-dichlorocyclohexane contain 12 hydrogen atoms.
