Chloromethane is a polar molecule while carbon tetrachloride is non polar though chloromethane has only one polar C-Cl bond while carbon tetrachloride has four polar C-Cl bonds. Explain. Concept Introduction: A molecule has polar bond if there is electro-negativity difference between to bonded atoms. The electro-negativity is the tendency to pull share pair of electrons towards itself. The polarity is created if the difference in the electro-negativity is greater than 0.4. Dipole exists in a molecule if it has polar bond. Dipole moment is the measure of polarity and it is a vector quantity (depends upon the direction).
