(a)In chemistry, a dipole usually refers to the separation of charges within a molecule between two covalently bonded atoms or atoms that have an ionic bond. For example, a water molecule (H2O) is a dipole. The oxygen side of the molecule carries a net negative charge, while the side with two hydrogen atoms has a net positive electric charge. The charges of a molecule, such as water, are partial charges, meaning they don't add up to a "1" for a proton or electron. All polar molecules are dipoles
