Is SO3- polar or non-polar

Answer 1

SO3 is a non polar molecule. Although the bonds between the S and O atoms are polar because S is more electronegative than O hence creating an electronegativity difference, the molecule is non polar. This is because the negative and positive centres are both loacted in the same place (at the S molecule) as they are all on the same plane and therefore there is no permanant dipole as the dipoles in the bond cancel each other out, therefore the molecule is non polar.

Answer 2

SO3 is a nonpolar molecule. The trigonal planar geometry of all oxygen atoms around the sulfur atom cancel the polarities of the bonds out.

Answer 3

nonpolar
