1 Raised over Fort McHenry on the morning of September 14, 1814, to signal American victory over the British in the Battle of Baltimore; the sight inspired Francis Scott Key to write The Star-Spangled Banner. 2  Preserved by the Armistead family as a memento of the battle.
London dispersion forces are a type of intermolecular force. They are relatively weak. They are also called induce-dipole induce-dipole interactions. 1  Present in non-polar molecules.  Due to non-systematic electron distribution where one molecule induces a dipole on another molecule.
Describe London dispersion forces (aka Van der Waals) and how they arise. Explain how to identify which molecules exhibit these forces. Show how to determine the relative strength of London forces in different molecules. This packet should help a learner seeking to understand London dispersion intermolecular forces.
