  1. Isomers can be divided into which 2 categories?
    • Constitutional
    • Stereoisomers
  2. Stereoisomers contain what?
    Chirality centers
  3. Constitutional isomers have different what?
    Connectivity
  4. Stereoisomers have the same connnectivity but different what?
    Orientation of groups in space
  5. Stereoisomers include which 2 groups?
    • Enantiomers
    • Diastereomers
  6. Chirality centers include which 2 groups?
    • Tetrahedral atoms with 4 different groups
    • Alkenes capable of cis-trans isomerism
  7. What are diastereomers?
    • Alkenes capable of cis-trans isomerism
    • Stereoisomers that are not mirror images
    • Chiral molecules
    • Have different physical properties (except for alkene diastereomers)
  8. What are enantiomers?
    • Nonsuperposable mirror images
    • Chiral molecules
    • Identical physical properties (except optical rotation)
  9. What is a racemic mixture?
    • A 50/50 misture of enantiomers
    • Also called racemate, racemic form
  10. What are chiral molecules?
    • Have nonsuperposable mirror images
    • Cause rotation of polarized light (optical activity)
  11. Different physical properties exist among compounds with what?
    A diastereomeric relationship
  12. What is a diastereomeric relationship necessary for?
    Resolution (the separation of 2 enantiomers)
  13. Stereoisomers that are not mirror images have what kind of relationship?
    A diastereomeric relationship
  14. What is resolution?
    The separation of enantiomers
  15. Achiral molecules include what?
    • Meso compounds
    • Alkene E (trans) or Z (cis) isomers
  16. Achiral molecules have what?
    • Superposable mirror images
    • An internal plane of symmetry
    • No optical activity
