The Lewis electron dot diagrams for are given below
The molecular geometry and polarity of the two substances are
Both the C–O and S–O bonds are polar due to the different electro negativities of the bonded atoms. However the molecule is linear and non polar due to the cancellation of the bond dipoles. In the molecule is bent and the bond dipole do not cancel. The polarities of the two substances differ because of the differences in geometries. This is a consequence of number electron domains around the central atom, 2 in and 3 in .
