Question

why h2o and carbon dioxide are nonpolar while SO2 is Polar?​

Answer 1

Answer:

Both S−O bonds and C−O are both polar due to the electronegativity difference between C and O,S and O. CO2 is a linear molecule, because it is symmetric. So the dipole moments of the 2C−O bonds cancel each other. While in SO2, two lone pairs are also present.

Answer 2

Answer:

CO2 is a linear molecule and the oxygen atoms on each end are symmetrical . Whereas the SO2 molecule is bent shaped and is polar because of the electronegativity difference between Sulphur and oxygen . Resulting in a net dipole moment . This doesn't occur in CO2 molecule hence its non polarity .
