  1. Chapter 5.3 – Organic Chemistry Science 10 p.244-251

  2. 5.3 Organic Compounds • Organic compounds contain carbon, and usually hydrogen. • “Organic” sounds like the compounds come from living things, but some do, and some don’t. • Inorganic compounds are compounds that do not have carbon (as well as some exceptions: CO2, CO and ionic carbonates)

  3. Why Carbon? • It has four electrons in its valence shell, which allows for more chemical bonding possibilities than any other element. • Long chains of carbon can form • Examples: petroleum and plastics

  4. Hydrocarbons: • organic compounds that contains only carbon and hydrogen. • Hydrocarbons are based on a carbon “backbone”, or chain, with hydrogen atoms added on the sides. • The simplest hydrocarbon is methane (CH4), followed by ethane (C2H6), propane (C3H8), butane (C4H10), and pentane (C5H12) • All hydrocarbons are flammable, and most are liquids at room temperature

  5. Alcohols: • are organic compounds with an -OH group off of the carbon chain. • The simplest alcohols are methanol (CH3OH), ethanol (C2H5OH) and isopropyl alcohol (C3H7OH). • Alcohols are very good solvents (they dissolve other substances) • Alcohols are generally very flammable Take the Section 5.3 Quiz
