Polar Molecules

Polar Molecules:

- Polar molecules have an overall charge separation.
       -Polar molecules are usually the ones that are unsymmetrical.
       -Non-polar are molecules are the ones that are symmetrical.
-Molecular dipoles only happened when there are unequal sharing of electrons in a molecule


Predicting Polarity:

-If the molecular are symmetrical, the pull of e- is usually balanced.
-There are two ways that molecules could be unsymmetrical:
      -Different atoms
      -Different numbers of atoms
