Question

2.32 Volcanoes and deep sea hydrothermal vents are both associated with sulfur-rich environments. Mount Etna is classed as a continuously degassing volcano and emissions of SO2 and H2S are around 1.5Tgy and 100Ggyi, respectively (Tg = 1012 g; Gg 10 g). (a) Draw Lewis structures for H2S and SO2, ensuring that the octet rule is obeyed by the S and O atoms. Your answer must be consistent with the fact that in SO2, the two sulfur-oxygen bonds are the same length. (b) Are H2S and SO2 polar or non-polar molecules? If polar, draw a diagram to show the direction of the molecular dipole moment. (c) In the troposphere, SO2 reacts with HO radicals. Construct an MO diagram for HO from H and O atoms, and deduce what you can about the bonding y respectively (Tg 10g: in HO
