Unlike metallic and ionic bonded compounds, covalent bonded compounds exist is units called "discrete molecules".
Because the atoms within the molecules do not change their relative position or bonding within the molecule during heating or when dissolved, they can be gases or molecular solutes. (Some molecular compounds will decompose or react with heating or with the solvent, but these are special cases).
Diatomic Hydrogen molecules are the simplest example. Each one contains two Hydrogen atoms covalently bonded.

Basically a 'discrete molecule' is a covalent molecule in which the intermolecular forces are really weak, hence the low melting and boiling points of these molecules.
The forces which act between these molecules are called Van Der Waals forces which is a intermolecular (between molecules) force. Since Van Der Waals forces are weak, only a small amount of energy is needed to break apart the molecules - so low m.p and b.p.
Make sure you don't get intermolecular forces confused with intramolecular forces, which hold an individual molecule together. They can be easily confused!
Van der Waals forces exist between all atoms and molecules.
