The homologous structures and the analogous structures of different species.
For a polar molecule<span>, your bonds will not cancel out. This means that in a </span>polar<span> bond, the electronegativity of the atoms will be different. For </span>nonpolar<span> bonds the electronegativity of the atoms will be equal. In a </span>polar<span> bond you will have an unequal sharing of electron pairs which causes a molecular dipole.</span>
