Chemical Properties of Group 18 Elements

Number of lone pairs of electrons on $\mathrm{Xe}$ atoms in ${\mathrm{XeF}}_2,{\mathrm{XeF}}_4,{\mathrm{XeF}}_6$ and ${\mathrm{XeO}}_4$ molecules are respectively.

The formation of ${\mathrm{O}}_2^{+}{\left[{\mathrm{PtF}}_6\right]}^{-}$ is the basis for the formation of xenon fluorides. This is because

Partial hydrolysis of ${\mathrm{XeF}}_6$ gives

The shape of ${\mathrm{XeOF}}_4$ is

Structure of ${\mathrm{XeO}}_2{ \mathrm{F}}_2$ is correctly represented by

In xenon fluorides most reactive in ${\mathrm{XeF}}_6, {\mathrm{XeF}}_4$ and ${\mathrm{XeF}}_2$ is

Which one of the following does not form during the hydrolysis of ${\mathrm{XeF}}_6?$

The shape of ${\mathrm{XeF}}_4$is 

${\mathrm{XeF}}_6$ on partial hydrolysis with water, produces a compound $\mathrm{X}.$ The same compound $\mathrm{X}$ is formed when ${\mathrm{XeF}}_6$ reacts with silica. The compound $\mathrm{X}$ is:

It is unfeasible for which of the following reactions of Xenon compounds to take place?
