2. How would you reduce an aldehyde to form a primary alcohol?
- add conc HCl and tin
- add NaBH4 and methanol
- add NaBH4 and ethanol
- add NaBH4 and reflux
3. How would you carry out a test to distinguish a carboxylic acid from a ketone?
- Heat gently with tollens reagent, silver mirror = carboxylic acid
- Add solid carbonate - fizzing as CO2 given off = aldehyde/ketone
- React with 2,4-DNPH, orange precipitate = aldehyde/ketone
- Oxidise with K2Cr2O7/H2SO4 - colour change = carboxylic acid
4. What observations would you record during the bromination of phenol?
- Solution changes colour from orange to green
- Solution changes colour from orange to brown
- Orange colour disappears - white ppt formed
- Orange colour disappears -> colourless solution
5. What are the reaction conditions and reagents for bromination of phenol?
- Bromine water, RTP
- HBr + RTP
- HBr + 50 degrees temp
