The noble gas compound prepared by Bartlett was

Xenon forms different types of compounds. One of the compounds is represented as $XeO_{n_1}F_{n_2}$. If the ratio of $n_1$ to $n_2$ is $1$ for this compound,then which of the following options is incorrect?

Assertion $(A)$: The boiling points of noble gases increase from $He$ to $Xe$.
Reason $(R)$: The interatomic van der Waals' attractive forces increase from $He$ to $Xe$.
The correct answer is:

Match List-$I$ with List-$II$ and select the correct answer using the codes given below the lists:

List-$I$	List-$II$
$(A) \ XeF_4$	$(1) \ \text{Distorted octahedral}$
$(B) \ XeF_6$	$(2) \ \text{Tetrahedral}$
$(C) \ XeO_3$	$(3) \ \text{Square planar}$
$(D) \ XeO_4$	$(4) \ \text{Pyramidal}$

Among noble gases from $He$ to $Xe$,only $Xe$ reacts with fluorine to form stable xenon fluorides. This is because xenon...

The order of liquefaction of noble gases is:
