CHEM 001 Class 9 Class Notes February 4, 2008 C. Cecil Cuppett, Ph.D. Chapter 4: 1. Organic chemistry is the study of carbon containing compounds like fuels, drugs, biological substances, and polymers (plastics). Many compounds contain only carbon and hydrogen (hydrocarbons). Many of these substances are fuels. Examples are methane, gasoline, oil, and coal. 2. Carbon always has 4 bonds to it and can form single, double, and triple bonds. Examples are methane, ethylene, and acetylene. 3. Hydrocarbons with only single carbon-to-carbon bonds are called alkanes . These substances make up many of the familiar compounds we experience; methane, propane, butane, octane (gasoline), heating oil, diesel fuel, and lubricating oils. 4. Hydrocarbons with double bonds are the starting materials for many plastic polymers. The double bond substances are called alkenes . 5. Carbon can have a triple bond between two atoms. These materials are called alkynes. The best known example is acetylene. 6.
