  • Alcohols
    • Basic info
      • CnH2n+OH
      • functional group is OH
      • capable of hydrogen bonding
      • 104.5 bond angle
    • made by
      • fermentation
    • oxidation
      • primary alcohol: turns into an aldehyde (if distilled) then a carboxylic acid
      • secondary alcohol: turns into a ketone if heated under reflux
      • tertiary alcohols do NOT react with oxgen as there is no free hydrogen to react.
  • fermentation
  • direct hydration of ethene
    • made by
    • elimination reactions

      • ethanol forms ethene and water
      • dehydration reaction
      • heat under reflux with conc H2SO4/H3PO4
    • OH and H atom are lost to form an alkene
      • elimination reactions
        • ethanol forms ethene and water
        • dehydration reaction
        • heat under reflux with conc H2SO4/H3PO4
