Molecular solids are substances where the atoms or molecules are held together by intermolecular forces, not by covalent or ionic bonds. They usually have lower melting and boiling points compared to ionic solids.

Van der Waals Forces: These are weak intermolecular forces that hold together non-polar molecules in molecular solids. Itโs like the minimal effort put into coordinating with group members during a school project.
Hydrogen Bonding: This is another type of intermolecular force, but stronger than van der Waals forces. It occurs between molecules containing hydrogen and highly electronegative elements such as oxygen, nitrogen or fluorine. Itโs like having a strong leader who keeps everyone on track in the group project.
These occur between polar molecules in molecular solids due to their positive and negative ends attracting each other. Itโs like when two students find common ground on an idea for the project and decide to work closely together.
