| Addition | A reaction in which atoms or groups of atoms bond to a double bond or triple bond; addition reactions include the addition of hydrogen (hydrogenation) and water (hydration) |
| Alkene | An unsaturated hydrocarbon containing a carbon-carbon double bond |
| Alkyne | An unsaturated hydrocarbon containing a carbon-carbon triple bond |
| Aromatic compounds | Compounds that usually have fragrant odors and often contain the ring structure of benzene |
| Benzene | A ring of six carbon atoms, each of which is attached to a hydrogen atom, C6H6 |
| Cis isomer | An isomer of an alkene in which the hydrogen atoms in the double bond are on the same side |
| Hydration | An addition reaction in which the components of water, H— and —OH, bond to the carbon-carbon double bond to form an alcohol |
| Hydrogenation | The addition of hydrogen (H2) to the double bond of alkenes or alkynes to yield alkanes |
| Monomer | The small organic molecule that is repeated many times in a polymer |
| Polymer | A very large molecule that is composed of many small, repeating structural units that are identical |
| Saturated hydrocarbon | A compound of carbon and hydrogen that contains the maximum number of hydrogen atoms |
| Trans isomer | An isomer of an alkene in which the hydrogen atoms in the double bond are on opposite sides |
| Unsaturated hydrocarbon | A compound of carbon and hydrogen in which the carbon chain contains at least one double (alkene) or triple (alkyne) carbon-carbon bond; an unsaturated compound is capable of an addition reaction with hydrogen, which converts the double or triple bonds to single carbon-carbon bonds |
