  1. Terminal alkene
    • alkene at the end
  2. internal alkene
    • alkene on the inside
  3. formula for an acyclic alkene
    CnH2n+2
  4. formula for a cyclic alkene
    CnH2n
  5. IUPAC naming of acyclic alkene
    • 1. Find longest carbon chain containing alkene
    • 2. Number chain
    •     ***alkene gets preference
    • 3. Alphabetize groups
    • 4. End with "ene"
  6. E/Z = cis or trans?
    • E = trans
    • Z = cis
  7. Cyclic alkenes:
    Number of alkene must be...
    1, 2
  8. How to make alkenes?
    • 1. POCl3 and pyruvate
    • 2. TsOH
    • 3. H2SO4
    • 4. Elimination
  9. Hydrohalogen
    Has an H and X on C's next to each other
  10. Addition:
    C=C --(X-Y)--> X-C-C-Y
  11. Hydrohalogenation
    • alkene + H-X ---> alkylhalides
  12. hydrohalogenation mechanism
  13. Markovnikov's rule
    • For all addition reactions, new H will be added to C with most H's attached.
    • Forms most stable intermediate
  14. Hydration
    • alkene + H2O and H2SO4 --> alcohol
  15. Hydration mechanism
  16. Halogenation
    • alkene + X2 (X = Cl, Br) --> [alkyl] dihalide
  17. halogenation stereochemistry
    halides are always anti in product
  18. what aren't F and I used in halogenation?
    • F = too reactive
    • I = too stable
  19. Halohydrin formation
    • alkene + X2 (Cl, Br) and H2O --> halohydrin
  20. halohydrin formation
  21. halohydrin formation:
    Water attacks the _________ carbon.
    more substituted
  22. halohydrin formation regioselectivity
    the X bonds to the less substituted carbon
  23. Hydroboration/Oxidation
    • alkene --(1. BH3, 2. H2O2/NaOH)--> alcohol
  24. Is hydroboration/oxidation concerted or stepwise?
    concerted
  25. Hydroboration:
    H adds to the more/less substituted side?
    more, so BH2 can be on less sterically hindered side
  26. Hydroboration:
    Does H & BH2 add as anti or syn?
    syn
  27. Hydroboration:
    What does the H2O2/NaOH do in the second step?2
    • replace BH2 with OH... magically. 
    • no need to show step, just arrow.
