Electron is transferred between atoms creating positive and negative ions that attract one another. Nonpolar covalent: electrons are shared equally (substances are hydrophobic aka water fearing) Polar covalent: electrons are shared unequally (substances are hydrophilic aka water soluble) Attractions occur between polar molecules in which h is bonded to o or n. The slightly positive hydrogen attracts the slightly negative o or n of a nearby polar molecule.
