Hi, everybody,
if O have higher Electronegative and are pull away from the central atom and make it nonpolar : O=C=O
and so SCI2? why is SCI2 polar but CO2 nonpolar? Thanks

Its because of the molecular shape. CO2 (O=C=O) is a linear molecule (180 o bond angle) and has a very orderly arrangement of its electrons. Dividing the molecule vertically through the central carbon or horizontally through all three atoms produces a mirror image of the electrons on either side of the dividing line. SCl2 is a bent molecule (probably 92 o or 93 o bond angle). The sulfur has two unshared pairs of electrons (4 electrons) on one side and two chlorine atoms with 8 electrons each (16 total) on the other side. This asymmetrical distribution of electrons makes it polar.

O=C=O
The oxygen on the left if pulling as hard as the oxygen on the right. So, overall, the molecule is non polar. S

SCl2 has the same shape as water. Cl Cl
Overall the dipole moment of this molecule points straight down the way I drew it.

You need to look at the molecular geometry which cam be found online or probably in your notes.
Basically, the two oxygen's cancel out because the vectors move in opposite directions.
