What are induced dipole-dipole interactions? (London forces)
What is the origin of induced dipoles?
Are induced dipoles temporary or permanent?
Induced dipoles result from interactions of electrons between molecules. The more electrons in each molecule ....(3)
What is the correlation between larger induced dipoles and boiling point?
What is van der Waals' forces?
What are permanent dipole-dipole interactions?
Polar molecules have ______ dipole interactions as well as permanent dipole-dipole interactions.
Draw a diagram showing permanent dipole-dipole interactions between hydrogen chloride, HCl, molecules.
HCl and F2 have the same number of electrons and the same shape, so the strength of the London forces in hydrogen chloride and fluorine should be similar. Why is HCl's boiling point higher than fluorine?

There are weak what forces that exist between molecules with a polarity?
Unlike induced dipole-dipole forces, permanent dipole-dipole interactions involves molecules with a permanent dipole and so are ________.
