What are intermolecular forces (IMFs)?

Attractive or repulsive forces between molecules. These forces dictate many physical properties, such as boiling point and melting point.

What are the types of IMFs?

1. Van der Waals forces (London dispersion forces): Weak, temporary attractions between all molecules due to instantaneous dipoles.
2. Dipole-dipole forces: Attractions between polar molecules.
3. Hydrogen bonding: Strong dipole-dipole interaction between molecules with H bonded to N, O, or F.

How to identify London Dispersion Forces?

Present in all molecules, regardless of polarity. Strength increases with molecular size (more electrons = more polarizable).

How to identify Dipole-Dipole Forces?

Occur between polar molecules, which have a net dipole moment. Look for molecules with polar bonds arranged asymmetrically.
