Fluorides of xenon
The important fluorides of xenon are xenon difluoride(XeF2), Xenon tetrafluoride(Xef4) and xenon hexafluoride. 1. Xenon difluoride(XeF2) It is prepared by heating a mixture of Xenon and fluorine in the ration 2:1 at 400 degree Celsius and 1 bar pressure in a sealed nickel tube. Xe + F2 ---Ni----> XeF2 XeF2 undergoes hydrolysis when treated with water an d evolves oxygen. 2XeF2 + 2H2O -------> 2Xe + 4HF + O2 In XeF2, Xenon is sp3d hybridised and the molecule has linear structure as shown. 2. Xenon tetrafluoride (Xef4) It is prepared by heating a mixture of Xe and F2 in the molecular ratio 1:5 at 400 degree Celsius and 6 atm in a sealed nickel tube. Xe + 2 F2 ---------> XeF4 XeF4 react with water and produces explosive XeO3 6 XeF4 + 12 H2O ---------> 2 XeO3 + 4 Xe + 3O2 + 24 HF In XeF4, Xenon is in sp3d2 hybridised state and has square planar geometry. 3. Xenon hexafluoride (XeF6) It is prepared by heating a mixture of xenon and fluorine in the ration 1:20 at 300 degree...
