One of the three equatorial positions is occupied by a nonbonding lone pair of electrons. It has a see-saw shape as it contains four bond pairs and one lone pair.As the one pair remained alone, two double pairs are bonded and form a bent shape. The three pairs of bonding electrons arranged in the plane at the angle of 120-degree. The electron geometry of SO2 is formed in the shape of a trigonal planner.
