Forces between Molecules
Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. However, there are also forces of attraction that can occur between molecules. Intermolecular forces (IMFs) are the attractions between molecules, which determine many of the physical properties of a substance. Figure \(\PageIndex{4}\) illustrates these different molecular forces. The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule.
