Discuss properties of :
(i) Xenon-fluoride compounds
(ii) Xenon-oxygen compounds

Explanation

(i) Xenon-fluoride compounds :
Physical properties : `XeF_2, XeF_4` and `XeF_6` are colourless crystalline solids and sublime readily at 298 K.
The structures of `XeF_2, XeF_4` and `XeF_6` are linear, square planar and distorted octahedral respectively and can be deduced from VSEPR theory.


Chemical properties : Xenon fluorides readily hydrolyse even by traces of water. For example :` XeF_2` hydrolyse to give Xe, HF and `O_(2)`
`2XeF_2(s) + 2H_2O(l)to 2Xe(g) + 4HF(aq) + O_2(g)`
Xenon fluorides react with fluoride ion acceptors to form cationic species and fluoride ion donors to form fluoroanions.
`XeF_(2) + PF_(5) to [XeF]^(+) + [PF_(6)]^(-)`,
`XeF_(4) + SbF_(5) to [XeF_(3)]^(+)[SbF_(6)]^(-)`
`XeF_(6) + MF to M^(+)[XeF_(2)]^(-)`, (M=Na, K, Rb or Cs)
(ii) Xenon-oxygen compounds : `XeO_3` is colourless explosive solid and has a pyramidal molecular structure.

`XeOF_4` is colourless volatile liquid and has square pyramidal molecular structure.
