Learn to determine if a molecule is polar or nonpolar based on the polarity between bonds and the molecular geometry (shape).

We start with the polarity between bonds using the electronegativity (EN) values on the Periodic Table provided. After that we’ll look at how the shape of the molecule, based on VSEPR, allows us to determine if the entire molecule is polar or nonpolar.

In the video you will also learn how to deal with unbonded electron pairs (lone) and how it affects the symmetry and polarity of molecules.

To help you learn and retain knowledge practice problems, with solutions, are provided throughout the video.
