Intermolecular forces – forces of attraction and repulsion that exist between particles

Intermolecular forces – forces of attraction and repulsion that exist between particles. London dispersion forces (LDF) weak, temporary, unpredictable forces that exist between all particles; ONLY force between nonpolar species.

Presentation Transcript

  1. Intermolecular forces – forces of attraction and repulsion that exist between particles

  2. London dispersion forces (LDF)weak, temporary, unpredictable forces that exist between all particles; ONLY force between nonpolar species

  3. Dipole-dipole attraction occurs when polar species are attracted to one another; examples include HCl, CHCl3, and PBr3

  4. hydrogen “bond-”ing – strongest type of dipole-dipole attraction; occurs when H is bonded to F, O, or N; examples include HF, H2O, and NH3
