Like bonds, molecules can also be polar. In a polar molecule, electron density is unevenly distributed throughout the molecule, resulting in regions of partial negative charge and regions of partial positive charge. Molecular polarity depends on both individual bond polarities and molecular geometry, the latter of which we can predict using VSEPR theory.
