  • Alkanes, Alkenes, Alcohols
    • alkANEs
      • CnH2n+2
      • Reactions
        • Substitution with halogens: UV
          • CH4 + Br2--->CH3Br + HBr
        • Cracking : turning long alkane chains into smaller ones
          • Aluminium oxide
          • 600-700 C
    • alkANEs
      • CnH2n
      • Reactions
        • Addition of Halogens : starts with an alkene, but when reacts with bromine (Br) the double bonds break = alkane (orange to colourless)
          • C2H4 + Br2 = C2H4Br2
        • Hydration of ethene
          • Phosphoric acid
          • 300 C
          • 60-70 atm
          • C2H4 + H2O = C2H5OH (ethanol)
          • Fermentation
            • Glucose + water = ethanol + C02
            • Anaerobic condition
            • 30-40 C
    • Alcohols
      • Reactions
        • Dehydration of ethanol
          • Aluminium oxide
          • Ethanol back to ethene and water
        • Fermentation
          • Glucose + water = ethanol + C02
          • Anaerobic condition
          • 30-40 C
