- - - - Increase with increased molar mass as greater polarizabilty
      - All molecules have london forces
      - momentary induced dipoles
    - - Bond between hydrogen and F,O,N
        
        Stronger than dipole-diple and London forces
    - - Between 2 polar substances
      - Permanent
- - - - A nonvolatile solute lowers vapor pressure of solvent
        
        Psolution = Xsolvent * Psolvent
      - Both volatile
        
        Ptotal = XaPa + XbPb
      - Ideal solution is when delta H = 0
      - Negative deviation is when lower than predicted
        
        Solute, solvent is similar so strong attraction. Delta H solution is large and negative
      - Positive deviation is when higher than predicted. Solute and solvent are dissimilar
