What is the difference between polar and non-polar molecules?

When you have a polar molecule, your bonds will not cancel out. This means that in a polar bond, the electronegativity of the atoms will attend to be different. For non-polar bonds the electro-negativity of the atoms will also be equal. In a polar bond you will have an unequal sharing of electron pairs which causes a molecular dipole. I hope this helps.
