Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. All the chlorine atoms share one electron from nitrogen to complete its octet leaving behind one lone pair on the nitrogen atom. NCl3 is a slightly polar molecule because of the small difference between the electronegativity of nitrogen and chlorine atom. Note: It is possible to have an existence of polar bonds in a nonpolar molecule, but due to symmetrical shape, these polarities get canceled with each other resulting in a nonpolar molecule. It has a pungent smell similar to that of chlorine. Greater the value of the dipole moment of a molecule more is its polarity. NCl3 molecule has one lone pair that leads to repulsion between electrons and the shape of the molecule is trional pyramidal. Question =  Is C2Cl4 polar or  nonpolar   ?
