There are two nuclei about the central atom, so the molecular shape is bent, or V shaped, with an HOH angle that is even less than the HNH angles in NH3, as we would expect because of the presence of two lone pairs of electrons on the central atom rather than one. The premise of the VSEPR theory is that electron pairs located in bonds and lone pairs repel each other and will therefore adopt the geometry that places electron pairs as far apart from each other as possible. In SO2, we have one BPBP interaction and two LPBP interactions.
