A diatomic molecule has a dipole moment of 1.2 D. If the bond distance is 1.0 A, fraction of an electronic charge on each atom is

μ=e×1 1.2×10−18 esu −cm=e×1.0×10−8cme=1.2×10−10 esu  charge on electron =4.8×10−10 esu  Thus, fraction of electric charge                                        =1.2×10−104.8×10−10=14=0.25
