Chemical Properties of Group 18 Elements

The correct statement about Xenon fluorides ${\mathrm{XeF}}_2, {\mathrm{XeF}}_4$ and ${\mathrm{XeF}}_6$ is

${\mathrm{XeF}}_6+\mathrm{MF}⟶{\mathrm{M}}^{+}{\left[{\mathrm{XeF}}_7\right]}^{-}$ In above reaction $\mathrm{M}$ can not be :

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

In a following reaction
${\mathrm{XeF}}_{\mathrm{n}}+\mathrm{CsF}⟶\stackrel{+}{\mathrm{Cs}}{\left[{\mathrm{XeF}}_{\mathrm{n}+1}\right]}^{-}$
Which value of $\text{'}\mathrm{n}\text{'}$ having maximum tendency to takes place this reaction.

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

Which of the following noble gas does not form clathrate compound? 

Consider the following reactions :
(i) ${\mathrm{PCl}}_3+3{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_3{\mathrm{PO}}_3+3\mathrm{HCl}$
(ii) ${\mathrm{SF}}_4+3{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_2{\mathrm{SO}}_3+4\mathrm{HF}$
(iii) ${\mathrm{BCl}}_3+3{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_3{\mathrm{BO}}_3+3\mathrm{HCl}$
(iv) ${\mathrm{XeF}}_6+3{\mathrm{H}}_2\mathrm{O}\to {\mathrm{XeO}}_3+6\mathrm{HF}$

Then according to given information the incorrect statement is

which of the following is an uncommon hydrolysis product of ${\mathrm{XeF}}_2$ and ${\mathrm{XeF}}_4?$

Which one of the following does not exist?

How many of the following compounds react with water to from ${\mathrm{O}}_2$ ?

${\mathrm{XeF}}_2, {\mathrm{XeF}}_6, {\mathrm{XeF}}_4, {\mathrm{Ca}}_3{\mathrm{P}}_2, {\mathrm{NH}}_3$

Which of the following noble gas is used in producing superconducting magnets?

Which mixture is used for respiration for the asthma patients? 

The reaction of solid $\mathrm{X}\mathrm{e}{\mathrm{F}}_2$ with $\mathrm{A}\mathrm{s}{\mathrm{F}}_5$ in 1:1 ratio affords

$\mathrm{X}\mathrm{e}{\mathrm{F}}_6$ on complete hydrolysis gives –

When ${\mathrm{P}\mathrm{t}\mathrm{F}}_6$ reacts with $\mathrm{X}\mathrm{e}\mathrm{n}\mathrm{o}\mathrm{n}$, the compound produced is-

Consider following properties of the noble gases.

I : They readily form compounds which are colourless.
II : They generally do not form ionic compounds.
III : Xenon has variable oxidation states in its compounds.
IV : The smaller He and Ne do not form clathrate compounds.
Select correct properties.

Which of the following does not form clathrate?

Asthma patient use a mixture of ..... for respiration

Which one of the following does not exist?
