What is a polar covalent bond?

A polar covalent bond is a bond in which the electrons are shared between two atoms, but unlike a covalent bond they are not shared equally. An example would be a hydrogen-chloride bond, where the chloride has a stronger electronegativity and therefore holds onto the electrons more tightly than does the hydrogen.
