ochem ch 8 reactions of alkenes part 1 (addition, electrophilic, pi bond, hydration, halogenation, h

  1. what is regiochemistry?
    which part of the reagent adds to which end of the double bond in an addition reaction
  2. Only during free radical addition of HBr does ____ ________ addition take place
    anti markovnikov
  3. Explain why in the following reaction Br goes to the less substituted carbon:

    because a tertiary free radical carbon is more stable than a secondary free radical carbon
  4. During oxymercuration-demurcuration, Hg(OAc)2 acts as a what? (electrophile or nucleophile
    electrophile
  5. in oxy-demurc., when Hg(OAc)2 becomes Hg(OAc) and forms two bonds with the substrate, what molecule does it form?
    it forms a mercurinium ion
  6. During oxy-demurc. which carbon does the H2O attack?
    the more substituted carbon
  7. alkoxymercuration-demurc takes place in a(n) ____ _____
    alcohol solvent
  8. In alkoxy-demurc., the alcohol forms a(n) ____ on the substrate
    ether
  9. does rearrangement occur during oxymercuration-demurc?
    no
  10. is hydroboration-oxidation markovnikov or anti-mark?
    anti-mark
  11. hydroboration occurs in ___ step(s), so therefore there is/isn't rearrangement
    one step so therefore there isn't rearrangement
  12. during hydroboration, the boron atom adds to the ____ substituted part of the double bond and the hydrogen adds to the ____ substituted part of the double bond
    less, more
  13. what is the hydroboration mechanism?

  14. __ moles of alkene can react with each mole of BH3
    3 moles of alkene
  15. when ethene reacts with borane, what molecule is formed?
