Is CO2 a Polar or Non-Polar Molecule?

Learn to determine if CO2 (Carbon dioxide) is polar or non-polar based on the Lewis Structure and the molecular geometry (shape). Join this channel to get full access to Dr. B's chemistry guides:    / @wbreslyn   We start with the Lewis Structure and then use VSEPR to determine the shape of the molecule. After that we’ll look at how the shape of the molecule, based on VSEPR, allows us to determine if the entire molecule is polar or nonpolar.

However, to determine if CO2 is polar we consider the molecular geometry. A polar molecule results from an unequal/unsymmetrical sharing of valence electrons. While there may be unequal sharing of electrons in the individual bonds, in a nonpolar molecule like CO2 these bonds are evenly distributed and cancel out. There is no net dipole and the Carbon dioxide (CO2) is non-polar.
