March 31,11 Polar Molecules

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 is usually balanced
-Molecules can be unsymmetrical in two ways
1)different atoms
2)different number of atoms
