        Fractioning column
        
        Temperature gradient
        
        Smaller chains have a lower B.P and go higher
        
        End up with a crude oil mixture seperated into different fractions
        
        From lowest to highest B.P. : Gases, Petrol, Kerosene, Diesel oil, Fuel oil
        
        Gases: Used as heating/cooking

  - - - Similar chemical properties and a trend in physical properties (within their group)
      - The bigger the molecule, the higher the B.P.
        
        Larger molecules have higher intermolecular forces, making them harder to break apart
  - - - Hydrogen + Oxygen --> CO2 + water + energy
        
        This is complete combustion
        
        With incomplete combustion (lack of O2), carbon monoxide is formed, which is toxic instead of carbon dioxide, and carbon (soot) is also formed
- - - - Coal
      - Oil
      - Gas
      - Harmful gases are released when burned
        
        Sulfur Dioxide
        
        Mixes with clouds to form acid rain
        
        Kills trees, damages limestone buildings and is harmful to life
        
        Carbon Dioxide
        
        Green house gases
        
        Global Warming
        
        Nitrogen Oxides
        
        Can cause acid rain and photochemical smog
        
        Causes breathing difficulties, headaches and tiredness
- - - - General formula: (C3H6)n
- - - - Carboxylic Acids
        
        Ends with "oic acid"
        
        Has the -COOH functional group
    - - Ends with "tyl" ... "noate"
      - The smells we can smell are from esters, from strawberries to glue, different esters have different smells
    - - Made from dicarboxylic acid with a diol, they can form a long polymer chain
