Represent the bonding in SF2 (F-S-F) with Lewis diagrams. Include the formal charges on all atoms. The dimer of this compound has the formula S2F4. It was isolated in 1980 and shown to have the structure F3S-SF. Draw a possible Lewis diagram to represent the bonding in the dimer, indicating the formal charges on all atoms. Is it possible to draw a Lewis diagram for S2F4 in which all atoms have valence octets? Expla in why or why not.
