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.
Answer:   Intermolecular forces are the forces of attraction and repulsion  that act between molecules or ions to influence the physical  properties of compouds.  i â¦ ntermolecular forces are forces that act between  stable molecules or between functional groups of macromolecules.   Answer:   Well the key word is molecule. In a substance like  water... There are many water molecules.o, there are permanent dipole-permanent dipole forces between molecules of CH3Cl. Also, let's not forget that like all other molecules, the â¦ re are also Van der Waal's forces(London forces).
