WebHowever, when polar covalent molecules dissolve in water, they do not ionize or separate into smaller particles like ionic compounds do. Compounds bound together with nonpolar covalent bonds tend to be hydrophobic and do not dissolve readily in water. This is because there are no charged or polar parts to interact with the polar water molecules.
