Atoms and non-polar molecules are electrically symmetrical.
All symmetrical molecules are non-polar and all asymmetrical molecules are polar. Both the atoms of a molecule have nearly the same electronegativity so that the electronic cloud is symmetrically distributed between both atoms. Thus known as electrically symmetrical.
- Nonpolar molecules occur when electrons are shared equally between atoms of a diatomic molecule
- when polar bonds in a larger molecule cancel each other out.
- Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.
