Why does sulfur dioxide has a dipole moment

1.	Why does sulfur dioxide has a dipole moment
Answer» because This molecule does not have a permanent dipole moment (i.e., the dipole moment of CO2 is ZERO). The requires the molecule to be linear because OXYGEN is more ELECTRONEGATIVE than carbon and therefore the C=O. ... The bonds in SO2 are also polar as the electronegativities of S and O are different, just like CO2.
