Oxidation of Alkenes

  1. Alkenes can also react with oxidising agents such as potassium permanganate(VII) to produce a diol.
  2. A diol is an alcohol with 2 hydroxyl group (-OH).
  3. This process is an addition reaction.
  4. Chemical reaction below shows the oxidation  reaction (also addition reaction) between ethene and potassium permanganate(VII).
  5. In the reaction, we use the square bracket with an O, [O], to represent the oxidising agent.
  6. The product produced is ethan-1,2-diol.
  7. During the reaction, the purple colour of acidified potassium manganate (VII) solution change to colourless.
