Dipole-Dipole Force

Dipole-Dipole Forces
A dipole-dipole force exists between neutral polar molecules
  • Polar molecules attract one another when the partial positive charge on one molecule is near the partial negative charge on the other molecule
  • The polar molecules must be in close proximity for the dipole-dipole forces to be significant
  • Dipole-dipole forces are characteristically weaker than ion-dipole forces
  • Dipole-dipole forces increase with an increase in the polarity of the molecule
