POLAR MOLECULES

Today in Chemistry class, we continues our discussion on Polar Molecules from last class.    

                     

        o       Polar Molecules have an overall charge separation.

        o       Unsymmetrical molecules are usually polar. 

              

o       Molecular dipoles are the result of unequal sharing of electrons in a molecule. A perfect example of this would be water bending, which Mr. Doktor demonstrated in class. Here’s a video showing it : 

o       If a molecule is symmetrical the pull of e- is usually balanced.

o       Molecules can be un-symmetrical in two ways :

    Different Atoms

    Different number of Atoms
