(D) CFCl 3. Since chlorine is more electronegative than carbon in the CFCl 3, it attracts electrons in the C — Cl bond. Hence, it has a net dipole moment. Therefore, the correct option is (C) SiF 4. Suggest Corrections.Dipole moment = Partial charge on atom * Bond length. Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product ...Physical Properties. Chloroform is a transparent liquid having a slightly sweet taste and an ether-like odour.
