Intermolecular forces are important because they help decide how easily a substance boils or melts. Let’s break it down:
Van der Waals Forces: These are weak attractions that happen between all molecules. For example, methane () is a gas with a low boiling point because of these weak forces.
Dipole-Dipole Interactions: These are stronger than Van der Waals forces and are found in polar molecules. Take hydrogen chloride () for example. It has a higher boiling point than methane because of these stronger interactions.
Hydrogen Bonding: This is a special and strong type of dipole-dipole interaction. Water () has a high boiling point because of hydrogen bonds. These bonds are very important for many life processes.
In short, the stronger the intermolecular forces, the higher the boiling and melting points of substances!
