The sulphur dioxide molecule contains 2 \sigma, 2 \pi bonds and one lone pair of electrons. S atom contains 6 valence electrons out of which it shares 2 electrons with 2 \mathrm{O} atoms to form 2 sigma bonds.It also shares 2 electrons with 2 \mathrm{O} atoms to form \pi bonds. The remaining 2 electrons appear as one lone pair of electrons. \mathrm{SO}_2 molecule has bent geometry. The \mathrm{S} atom undergoes \mathrm{sp}^2 hybridization.
