All the bonds are covalent, and there will not be a big dipole moment. Thus, CH 4 is a nonpolar molecule. The difference between polar and nonpolar molecules can thus be found by the vectors of partial charge resulting from each bond. Similarly, knowing the bond length and observed dipole moment of HCl, the % ionic character can be found to be 18%. Thus it can be seen that while HI is essentially covalent, HCl has significant ionic character. Note that by this simplistic definition, to achieve 100 % covalent character a compound must have an observed dipole moment of zero.
