Polar Molecules

-Polar molecules have an overall charge separation
-unsymmetrical molecules are usually polar
-molecular dipoles are the result of unequal sharing of electrons in a molecule

Predicting Polarity
-if a molecule is symmetrical the pull of e-(electrons) usually balance
-Molecules can be symmetrical in two ways
  *different atoms
  *different number of atoms

These are examples of molecules with polar and non-polar bonds
