    • Alcohols
      Extremely useful molecules, e.g. as fuels, solvents
    • Ethanol
      Alcohol found in alcoholic drinks
    • Methanol
      Alcohol with one carbon atom
    • Alcohols
      • Homologous series, have the same functional group
    • Structural formula

      Simpler form of showing molecule structure
    • First four alcohols
      • Methanol (1 carbon)
      • Ethanol (2 carbons)
      • Propanol (3 carbons)
      • Butanol (4 carbons)
    • Alkane name
      Alcohol name based on it (e.g. ethane -> ethanol)
    • Ethanol
      One of the most important alcohols
    • Producing ethanol by hydration of ethene
      1. High yield
      2. Requires high temperature and energy
      3. Uses non-renewable crude oil
    • Producing ethanol by fermentation
      1. Uses sugar solution and yeast
      2. Requires temperature around 30°C
      3. Must be anaerobic (without oxygen)
      4. Produces ethanol and carbon dioxide
      5. Ethanol solution needs to be purified by distillation
    • Fermentation to produce ethanol
      • Advantages: low temperature, uses renewable plant-based sugars
      • Disadvantage: produces aqueous ethanol solution that needs distillation
    • You'll find plenty of questions on alcohols in the revision workbook
