3.3.5.3. elimination reactions

• how can alkenes be formed?

  dehydration of alcohol - water removed from the molecule
• dehydration conditions


  excess of hot sulphuric acid is added and aluminium oxide used as a catalyst
• elimination mechanism

  
• what does this elimination reaction mean?

  addition polymers can be produced from fermentation without the need for crude oil - non-renewable resource
• what does fermentation produce?

  the primary alcohol which is then dehydrated to produce an alkene used in the production of addition polymers
