Covalent bonds can be polar or non-polar, and so can the overall compound depending on its shape. When a bond is polar, it creates a dipole, a pair of charges (one positive and one negative). If they are arranged in a symmetrical shape, so that they point in opposite directions, they will cancel each other.Organic Chemistry (Schaum's Outlines) 4th ed Jan 09, 2018 · The are two types of molecular bonds: polar bonds and non-polar bonds. In polar bonds, the molecular bond is unevenly shared between atoms; in non-polar bonds, the electrons are evenly shared between the two atoms. Covalent Bonding. Sharing. Covalent Bonding.
