Chapter 7, Question 36 Describe the bonding of sulphur dioxide, SO2. Select all the apply. O Four valence electrons occupy the delocalized it bonding orbitals. Two valence electrons occupy the delocalized Tt bonding orbitals. The Lewis structure indicates the presence of one it bond. The Lewis structure indicates the presence of two it bonds. The sulphur has SN=3, so has sp2 hybrid orbitals. Because sulphur is a third-row element, its 3d orbitals contribute to the extended it bonding orbitals. Click...
