alkene

• 2. Addition bromine / test

  
  

  3. Addition: 1 product

  4. C=C split: test C=C

  5. Orange/brown -> colorless

  6. + Br2 -> Dibromoethane
• 7. Addition hydrogen (hydrogenation)

  8. + H2 -> saturated alkane

  9. Nickel catalyst

  10. High tmp
• 11. Addition steam

  12. Alkene + water -> alcohol

  13. Phosphoric acid catalyst

  300 C

  60 atm
• 1. Cracking

  long chain -> short alkane + alkene + sometimes Hydrogen

  Polymer -> monomer

  thermal decomp (need heat)

  
  

  500 C

  2-70 atm

  silica/alumina catalyst
