The noble gas compound prepared by Bartlett was

$XeF_2$ and $XeF_6$ are separately hydrolysed,then:

In the preparation of compounds of $Xe$,Bartlett had taken $O^{+}_2 Pt F^{-}_6$ as a base compound. This is because

Which of the following is not obtained by the direct reaction of constituent elements?

In reaction $(1)$,$XeF_6$ undergoes complete hydrolysis to form $HF$ and $X$. In reaction $(2)$,$XeF_6$ undergoes partial hydrolysis to form $HF$,$Y$,and $Z$. The products $X, Y, Z$ respectively,are

The difference in the oxidation state of $Xe$ between the oxidized product of $Xe$ formed on complete hydrolysis of $XeF_4$ and $XeF_4$ is
