In the present study, we directly estimate how each sulfur atomic orbital contributes to the chemical bonding in various fluorides. We have already... 

Among the sulfur fluorides, SFg, 15.28, stands out for its high stability and chemical inertness. It can be made by burning S in F2, and is commercially available, being widely used as an electrical insulator. Its lack of reactivity (e.g. it is unaffected by steam at 770 K or molten alkalis) is kinetic rather than thermodynamic in origin. The value of A G° for reaction 15.53 certainly indicates thermodynamic spontaneity. The bonding in SF5 was discussed in Section 4.7. 

Much of the chemistry of oxygen can be rationalized in terms of its electronic structure (2s 2p ), high electronegativity (3.5) and small size. Thus, oxygen shows many similarities to nitrogen (p. 412) in its covalent chemistry, and its propensity to form H bonds (p. 52) and double bonds (p. 416), though the anionic chemistry of 0 and OH is much more extensive than for the isoelectronic ions N , NH and NH2. Similarities to fluorine and fluorides are also notable. Comparisons with the chemical properties of sulfur (p. 662) and the heavier chalcogens (p. 754) are deferred to Chapters 15 and 16.
