Forces of Attraction

  • Dipole-Dipole
  • London Dispersion Forces
  • Hydrogen Bonding
Descriptions of the Intermolecular Forces:

Dipole-Dipole: Electrostatic attraction between the positive end of one molecule and the negative end of another.
London Dispersion: Because electrons are constantly moving, one end of a non-polar molecule is either temporarily positive or negative. Temporary dipoles are created, and two non-polar molecules may attract each other. Dispersion forces act on all molecules.

Hydrogen Bonding: Temporary bond forms between an H atom of a molecule and a N, O, or F atom of another molecule.

  1. Great descriptive words Allie! You were bound to be a scientist someday. Because of you I better understand intermolecular forces!

  2. Great job explaining the forces. You explained them very well and detailed. I completely understand. The intermolecular forces are also correct.

  3. Allie, the definitions of the intermolecular forces are very thorough and well explained. Also the diagrams are a great depiction of the forces described.
