SO3 is a non polar molecule. Though the bonds between the S
and O atoms are polar as a result of S is extra electronegative than O
therefore creating an electronegativity distinction, the molecule is non
polar. It’s because the unfavorable and constructive centres are each
loacted in the identical place (on the S molecule) as they’re all on
the identical aircraft and subsequently there isn’t any permanant dipole because the
dipoles within the bond cancel one another out, subsequently the molecule
is non polar.
