$XeF_6$ on hydrolysis produces

The number of lone pair of electrons present in the valence shell of Xenon $(Z=54)$ in $XeOF_4$,$XeF_4$,$XeF_2$,and $XeF_6$ are respectively:

Liquid $X$ is used in a bubble chamber to detect neutral mesons and gamma photons. Then, $X$ is

In the preparation of compounds of $Xe$,Bartlett had taken $O_2^+PtF_6^-$ as a base compound. This is because:

Under ambient conditions,the total number of gases released as products in the final step of the reaction scheme shown below is:

Assertion $(A)$: $Xe$ atoms in $XeF_2$ are $d^2 s p^3$ hybridised.
Reason $(R)$: $XeF_2$ molecule does not follow the octet rule.
Which of the following is correct?
