- 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
- Alkene to a Primary Alcohol and Secondary Alcohol
