The first compound of inert gases was prepared by scientist Neil Bartlett in $1962$. This compound is

Xenon reacts with fluorine at $873 \ K$ and $7 \ bar$ to form $XeF_4$. In this reaction, the ratio of xenon and fluorine required is

Given below are two statements:
Statement-$I$: Noble gases have very high boiling points.
Statement-$II$: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this,they are liquefied at very low temperatures. Hence,they have very high boiling points.
In the light of the above statements,choose the correct answer from the options given below:

Find the product of the following reaction,when $Xe$ is taken in excess:
$Xe_{(g)} + F_{2(g)} \longrightarrow ?$

Hydrolysis of $XeF_4$ gives $HF$,$O_2$,$Xe$ and '$X$'. The structure of '$X$' is

Which noble gas is most soluble in water?
