Lewis structure of SO2 molecule is O=
S
..
→
O . This indicates that S atom is surrounded by two sigma bond pairs and one lone pair.
Thus according to VSEPR theory the spatial arrangement of these three electron pairs around the central atom should be trigonal planar . But due to the presence of lone pair of electrons there are bond pair - lone pair repulsions and thus the shape of SO2 is not trigonal planar but it is angular or bent shaped .
and for CO2 the lewis structure is O=C=O . The central atom C has two bond pairs only , there are no lone pairs. Thus according to VSEPR theory this molecule has a linear structure due to presence of two bond pairs and no lone pairs.
