The net dipole moment is 1.6 Debye. Does SCl2 have a dipole moment? The molecular geometry and its symmetry are good indicators of “polar” vs “nonpolar.” Consider CCl4 —- it is tetrahedral, like CH2Cl2, but CCl4 is symmetrical. As people say, Cl-S-Cl is polar because it is “bent” with a bond angle close to a right angle. The resultant of the two bond dipoles has its negative end away from S. However, the partial negative charge due to the lone pairs points opposite to the negative end of the resultant. Chemistry: An Atoms First Approach. Dip ole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge (1 Debye eq uals $$3.34 \times 10^{-30}\; C\, m$$).
