Polar Molecules

- polar molecules have an overall charge seperation
- unsymmetrical molecules are usually polar
molecule dipoles: are resulted of unequal sharing of electrons in a moleculE

Predicting Polarity

- If a molecule s symmetrical the pull of electrons are usually balanced
- molecules can be un-symetrical in 2 ways:
1. different atoms
2. different number of atoms

EXAMPLE:

CO2     Non polar (because it is symmetrical)
