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.

Water bending is a good example of this.



Predicting Polarity

If a molecule is symmetrical the pull of e- is usually balanced. Molecules can be un-symmetrical in two ways:

-different atoms
-different numbers of atoms

Example: Find Polarity



Right now we are not too concerned about the shape of molecules but if we were we could use the VSPER method to figure the shapes out.
