The shape of the molecule can be predicted by using the principles of the valence shell electron pair repulsion theory. Although C and S have very similar electronegativity values, S is slightly more electronegative than C, and so the C-S bond is just slightly polar. Also state whether the neutral molecules are polar or nonpolar. Their vector sum is zero, so CO2 therefore has no net dipole. In contrast, the H2O molecule is not linear (Figure \(\PageIndex{2b}\)); it is bent in three-dimensional space, so the dipole moments do not cancel each other. company owns shopstyle codycross abigail western area 51; wax candy with juice inside troy mi ..
