Nh3 intermolecular forces. Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions). They are weak compared to the intramolecular forces, the forces which keep a molecule together. Hydrophobic interactions describe the relations between water and hydrophobes (low water-soluble molecules).

The amount and strength of intermolecular forces tells essentially how much energy we need to change physical states. If we consider water for example, changing solid water (ice) to liquid water is a physical change where we need to overcome the intermolecular forces of the water molecules and separate them. The amount of energy we need to add ...
