  1. Define Polycyclic compound
    A compound containing more than one ring
  2. Define Heterocyclic compound
    A ring stucture that contains an atom other than carbon
  3. Define Constitutional isomer
    Same molecular formula, different structures

    Structural isomer - different connectivity
  4. Define gauche structure
    Two carbons that are 1 and 4 relative to each other 60 degrees apart
  5. Define Hybrid Orbitals
    e.g. Sp^3- where stomic orbitals hybridize to form molecular orbitals
  6. Define Steric effects
    e- repulsion or neighboring groups
  7. Define Londn dispersion forces
