Two dichloroethylene molecules with the same chemical formula 1C2H2Cl22, but different arrangements of atoms are shown. (b) Which form of dichloroethylene has a dipole moment of 2.39 D, and which has a dipole moment of 0.00 D?

(a) Does CS₂ have a dipole moment? If so, in which direction does the net dipole point? (b) Does SO₂ have a dipole moment? If so, in which direction does the net dipole point?

(b) It turns out that ozone, O₃, has a small dipole moment. How is this possible, given that all the atoms are the same?

(c) Does the molecule BF₂Cl have a dipole moment?
