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
  • Bromine water, halogen carrier
