While reacting with nonmetals, both form covalent compounds, for instance, H2O, H2S, CO2, and CS2. terminal atoms are fluorine. From the molecular geometry of carbon diselenide, it is clear that it is a primary compound with no deviation from the linear behavior whatsoever. In this MO we can see that the AO of sulfur, which is on the left-hand side associates with the AO of oxygen on the right-hand side. But the electron geometry of SO2 is trigonal planar. The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. Oxygen does not react with water while when steam is passed through boiling sulfur, a little hydrogen sulfide and sulfur dioxide are made.
