The polarity of a molecule is directly proportional to the difference between the electronegativity of atoms. CH4 has 4 CH bonds, the angle between them is 90 degrees, so it's symmetric, no dipole moment. It is usually observed that the symmetrically shaped molecules are nonpolar in nature whereas the asymmetrically shaped molecules are polar.eval(ez_write_tag([[250,250],'techiescientist_com-large-leaderboard-2','ezslot_8',107,'0','0'])); Note: In case, if the nonpolar molecules also have the presence of polar bonds within them, the polarity of such bonds gets canceled by each other due to the symmetric shape of the molecule. Electronegativity: the electronegativity of an atom is the measure of the strength of an atom to attract the shared bonded electron pairs towards its side.
