SO2 - Sulfur Dioxide:

First draw the Lewis dot structure:
SO2 Lewis Structure
Electron geometry: trigonal planar. Hybridization: sp2

Then draw the 3D molecular structure using VSEPR rules:

The molecular geometry of SO2 is bent (approx. 120 degrees) with asymmetric charge distribution on the central atom.
Therefore this molecule is polar.
