How to tell if a molecule is symmetrical - Polar Molecules Part 2 - Real Chemistry

In this video we continue our series on determining if a molecule is polar. In the first video in the series, we learned how to determine if a bond is polar. A molecule is polar if it contains a polar bond AND it is asymmetrical. In this video we turn to this second requirement. We learn how to tell if a molecule is asymmetrical by looking for either one of two key features 1) A lone pair on the central atom OR 2) Different terminal atoms. If either are present, the molecule is asymmetrical. We discuss two exceptions to the lone pair rules (linear or square planar molecular geometries.) Lastly, we apply these rules to a series of examples to determine if the molecule are symmetrical or not.
