  • Formations
    • Alkene to a Primary Alcohol and Secondary Alcohol
      • Conditions: steam, 300C, 60-70 ATM, phosphoric acid catalyst
    • Primary alcohol to an Aldehyde
      • Oxidation Reaction
      • Conditions: acidified potassium dichromate (H+/K2CrO7). The aldehyde must be distilled
        • colour change from orange to green
    • Primary alcohol to a carboxylic acid
      • Oxidation Reaction
      • Conditions: acidified potassium dichromate, heat under reflux
      • change colour from orange to green
      • To test if a carboxylic acid is made, it will fizz when carbonate is added
      • when a carboxylic acid and a primary alcohol join, an ester is formed
        • conditions: remove water, use a H2SO4 catalyst and heat it
    • Secondary alcohol to ketone
      • Conditions; acidified potassium dichromate, heat under reflux and the colour change is orange to green
    • Tertiary alcohol
      • No change with acidified potassium dichromate, they are not oxidised
