Chemistry: Intermolecular Forces
by Texas Instruments - Simulation Lesson

Published on July 11, 2011

Objectives

  • Students will be able to distinguish intermolecular and intramolecular forces.
  • Students will understand the differences between dipole-dipole interactions and induced dipole-induced dipole (London dispersion) interactions.

Vocabulary

  • dipole-dipole interactions
  • dipole moment
  • induced dipole-induced dipole interactions
  • intermolecular forces
  • intramolecular forces
  • London dispersion forces
  • van der Waals forces

About the Lesson

  • In this lesson students will first observe the changing charge cloud that surrounds a single polar molecule (HCl) and a single non-polar molecule (Cl2).
  • Next students are shown the lines of force that develop between adjacent HCl molecules and adjacent Cl2 molecules. These simulations will give students new insights into why molecules attract each other. They will also explore the different types of intermolecular interactions.
