University of Colorado: Ph Et Interactive Simulations: Molecule Polarity
When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works...
