  3. 1 - $200 • What is a species with a lone, unpaired electron called? • A free-radical

  4. 1 - $300 • What is a positively charged substance desired negative charge called? • An electrophile

  5. 1 - $400 • What is the type of addition that occurs when addition to an alkene occurs on the same side of the plane of atoms? • Syn Addition

  6. 1 - $500 • What is the name of the rule that states that the nucleophilic part of the reagent will bind with the most stable carbon of the substrate? • Markovnikov’s rule

  7. 2 - $100 • What is produced through the dehydration synthesis reaction between two primary alcohols? • An ether

  8. 2 - $200 • What is the best acid to use to catalyze a dehydration synthesis reaction (in part due to its strong dehydrating ability)? • H2SO4 (sulfuric acid)

  9. 2 - $300 • What ester is made when reacting butyric acid (butanoic acid) with methanol? • Methyl butanoate

  11. 2 - $500 • What are the products of COMPLETE combustion? Carbon Dioxide & Water Carbon monoxide & carbon are produced when there are insufficient amounts of oxygen.

  12. 3 - $100 • What type of alkene is ethene; symmetrical or unsymmetrical? • symmetrical

  13. 3 - $200 • What is the major product for the electrophilic addition reaction between propene and H-Br? • 2-bromopropane

  14. 3 - $300 • What is the first & slowest step of any electrophilic addition reaction? • What is the electrophile of this reaction? • The formation of the carbocation • The hydrogen (from either the H-X or from H-OH)

  15. 3 - $400 • What are the major & minor products of the following reaction?

  16. 3 - $500 • What is the major product of the following:

  17. 4 - $100 • Hydrogenation reactions are catalyzed by metals that adsorb hydrogen to their surface. What is an example of a metal that would be suitable to catalyze this type of reaction? • Pt, Rh, or Ni
