| Organic Compounds | Compounds that contain the element carbon; there are a few exceptions such as carbon monoxide, carbon dioxide, and carbonates. More than 90% of all compounds are organic compounds |
| Hydrocarbon | A compound made up of only carbon and hydrogen atoms |
| Saturated Hydrocarbons | Hydrocarbons containing single-bonded carbon atoms |
| Unsaturated Hydrocarbons | Hydrocarbons such as ethene and ethyne that contain double or triple bonds between carbon atoms |
| Isomers | Compounds that have identical chemical formulas but different molecular structures and shapes |
| Aromatic Compound | A compound that contains the benzene ring structure |
| Substituted Hydrocarbon | Has one or more of its hydrogen atoms replaced by atoms of other elements |
| Alcohol | Formed when OH groups replace one or more hydrogen atoms in a hydrocarbon |
| Biomass | Refers to all animal and plant material, both dead and alive |
| Biogas | Is mainly methane, just like natural gas |
| Energy Farming | Involves growing plants for use as fuel |
| Gasohol | Is a combination of ethanol and gasoline |
| Polymers | Are huge molecules made of many smaller organic molecules that have formed new bonds and linked together |
| Proteins | Make up many of the tissues in your body, such as muscles and tendons, as well as hair and fingernails |
| Nucleic Acids | Are polymers that control the activities and reproduction of the cells |
| Carbohydrates | Are organic compounds in which there are twice as many hydrogen atoms as oxygen atoms |
| Lipids | Fats, oils, and related compounds make up a group of organic compounds called lipids |
