Molecules are classified as polar when the atoms comprising the molecule are arrayed in a way that one end of the molecule has a net negative charge while the opposite and has a net positive charge. A water molecule. Blue represents positive charge areas, red negative charge areas ... WebJul 3, 2024 · A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.
