Fractional Distillation and Hydrocarbons

View mindmap
  • Organic Chemistry
    • Hydrocarbons
      • Only contain Hydrogen and Carbon atoms
      • Alkanes all have C-C single bonds
        • Alkanes:   Simpliest type of hydrogen you can get
        • Homologous Series: Group of organic compounds that react in a similar way
        • Saturated Compounds
        • First four alkanes: Methane, Ethane, Propane and Butane
      • Hydrocarbon Proporties change as the chain its longer
        • Shorter=more runny, less viscous, lower boiling points, different uses
      • Complete combustion: occurs when there's plenty of oxygen
        • hydrocarbon + oxygen --> carbon dioxide + water
        • During combustion, both carbon and hydrogen from the hydrocarbon are oxidised
    • Fractional Distllation
      • Used to separate hydrocarbon fractions
      • How it works
        • Oil is heated until most of it is turned to gas . The gases enter a fractional column
