Simple Molecular Compounds
Simple Molecular Compounds
- Covalent substances tend to have small molecular structures, such as Cl2, H2O or CO2
- These small molecules are known as simple molecules
- Hydrogen (H2), chlorine (Cl2), oxygen (O2), nitrogen (N2), hydrogen chloride (HCl), water (H2O), ammonia (NH3) and methane (CH4) are also examples of simple molecules
- Iodine is a simple molecule and can be represented but it exists as a crystalline structure involving a regular structure held together by weak London dispersion forces
