Covalent (Simple) Molecules have a low melting point and boiling point.

- Simple covalent molecules have ❌ covalent bond within the atoms.

- However, they have ❌ inter-molecular attraction force, known a Van der Waal force.

- So it requires ❌ energy to break the attraction force.

Covalent molecules do not dissolve in water.
- Covalent molecules are mostly ❌.
Water is a ❌.
- Non-polar molecules like H2, Cl2, N2 and CH4 will ❌.
- However some molecules like HCl, NH ❌.
