This is a violent reaction under cold conditions, and white phosphorus behaves even more dramatically. The products were identified by fluorine nmr spectroscopy and the conditions under which fluorine exchange occurs were briefly investigated. Phosphorus pentafluoride was first prepared in 1876 by the fluorination of phosphorus pentachloride using arsenic trifluoride, which remains a favored method: 3 PCl 5 + 5 AsF 3 → 3 PF 5 + 5 AsCl 3. From Fig. Explosive reaction with alkaline metals (sodium, potassium), urea. However, in the case of the FAP and NTf(2) based systems, a cation dependence was observed, with relatively poor wear resistance obtained in the case of an imidazolium FAP and two pyrrolidinium NTf(2) salts, probably due to tribocorrosion caused by the fluorine reaction with the aluminium substrate. Phosphorus combines easily with the halogens. Phosphorus atom would play a role of the key reaction center and participates in di-rect interaction with a substrate in contrast to fluorine. 1 (a). Write the balanced chemical equation for the reaction with enthalpy change in the equation. Fluorine is a gas consisting of two fluorine atoms bonded together (F2).
