  • Organic Chemistry and Polymers
    • Alkanes
      • Carbons all singularly bonded together
        • "Saturated"
          • liquid fats are unsaturated=healthy but hard to contain
      • C(n)H(2n+2)
      • Fuels (NB combustion= CO2 and H2O
    • Isomers= compounds with same molecular formula but different displayed formula
    • Meth, eth, prop, but, pent
    • Hydrocarbons
    • Alkenes
      • Double covalent bond C=C
      • C(n)C(2n)
      • Test for alkenes
        • pure liquid bromine or solution of bromine
          • yellowy-brown to colourless (or dark red to colourless)
      • Hydrogenation
        • Makes alkanes
        • Oils to solid fat
      • reaction with steam
    • Cracking
      • Alkanes
        • Carbons all singularly bonded together
          • "Saturated"
            • liquid fats are unsaturated=healthy but hard to contain
        • C(n)H(2n+2)
        • Fuels (NB combustion= CO2 and H2O
      • Forms mixture of products, fractional distillation
        • Alkanes: fuels mainly petrol
        • Alkenes: alcohols, polymers, useful chemistry
      • no air, heat and a catalyst
