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 Celsius and 60 atm in a nicked vessel.
Xe + 3 F2 --------> Xe F6
XeF6 Undergoes slow hydrolysis with atmospheric moisture producing highly explosive XeO3.
XeF6 + 3H2O --------> XeO3 + 6 HF
XeF6 molecule possesses distorted octahedral structure. The Xe atom in XeF6 is in sp3d3 hybridisation.
