Resumen del Recurso

Alkanes and Alkenes
  1. Alkanes
    1. Saturated hydrocarbons
      1. Have single bonds only
        1. Means they are saturated with hydrogen
      2. Alkenes
        1. Unsaturated hydrocarbons
          1. Have at least one double bond
          2. Addition reactions
            1. Carbon-Carbon double bond in alkenes means another atoms can be added
              1. Hydrogen and Bromine can be added in this way
              2. When hydrogen is added to an alkene (hydrogenation), the corresponding alkane is formed.
                1. When Bromine is added to an alkene it forms a dibromoalkane.
                  1. Double bond breaks and 2 bromine atoms attach
                    1. Its useful as it can be used to test for presence of an alkene
                      1. Brown/orange bromine water will react with alkenes and its colour disapears as the product formed is colourless
