INTERMOLECULAR FORCES :

• Intermolecular forces play and important role in chemistry.
• They are attractions and repulsions felt between atoms and molecules.
• They are different depending on the chemical bond.
• When you break a chemical bond, you obtain a new material that reacts differently with other chemicals.
• When an intermolecular attraction is broken, the chemical formula and chemical reactivity don't change.
• Intermolecular forces can determine how quickly a chemical reaction occurs , or if it can even occur.
• These forces determine whether a material will be a liquid, a solid, or a gas at given temperatures.
