Alcohols (Organic) Flashcards
1
Q
Describe the three reactions that could occur when a primary alcohol is oxidised?
Give general equations. (How would you write the oxidising agents in the reaction)
A
- Oxidation:
1. reflux; primary alcohol + K2Cr2O7 + H2SO4 —> carboxylic acid + H2O
2. heat and distil off product; primary alcohol + K2Cr2O7 + H2SO4 —> aldehyde + H2O
3. heat and distil aldehyde from 2; aldehyde + K2Cr2O7 + H2SO4 —> carboxylic acid

Q
How do you do reflux? (Reactions of alcohols)
A
- Distillation without separating the reactants, where the gases cool before they can escape.
