  1. Thermodynamic control
    reaction in which the product distributions is determined by the relative energies of the products.
  2. Kinetic control
    reaction in which the product distribution is determined by the heights of the different transition states leading to products
  3. Hammond Postulate
    states the transition state for a reaction will more closely resemble the higher energy molecule (i.e. the products for an endothermic reaction and the reactants for an exothermic reaction)
  4. Equilibrium constant
    difference in energy between the starting materials and the products
  5. Enthalpy
    heat of reaction or measure of the bond energy changes in a reaction
  6. entropy
    measure of the change in order between the starting materials and products
  7. exergonic
    reaction where products are more stable than reactants
  8. endergonic
    reaction where reactants are more stable then products
  9. Le Chateliers principle
    states that a system at equilibrium responds to stress in a way to relieve the stress
  10. 1st order reaction
    reaction rate depends solely on the concentration of one species
  11. 2nd Order reaction
    reaction rate depends on the concentration of two species
  12. Pseudo 1st order reaction
    reaction where the concentration of one of the reactants does not change during the reaction
  13. microscopic reversibility
    states that if the mechanism of the forward reaction is known, then the mechanism of the reverse reaction must also be known
  14. Syn elimination
    elimination where the dihedral angle between C-L and C-H is 0°
  15. Anti elimination
    elimination where the dihedral angle between C-L and C-H is 180°
  16. regiochemistry
    outcome of a reaction where more than one orientation of substituents is possible in the product
  17. hoffmann
    less stable alkene
  18. saytszeff
    more stable alkene
  19. 3 seperation techniques
    crystallization, distillation, chromatography
  20. 4 structural determination methods
    NMR spectroscopy, IR spectroscopy, Mass spectrometry, UV/vis spectroscopy
  21. hydration
    addition of water to a pi bond
  22. hydrolysis
    formation of an alcohol
