Which noble gas has the lowest boiling point?

Which element among the following does $NOT$ form diatomic molecules?

$Xe + 2F_2 \xrightarrow{573 \ K, \ 60.70 \ bar} A$
What is $A$?

Match the Xenon compounds in Column-$I$ with their structures in Column-$II$ and assign the correct code.

Column-$I$	Column-$II$
$(a) XeF_{4}$	$(i) \text{Pyramidal}$
$(b) XeF_{6}$	$(ii) \text{Square planar}$
$(c) XeOF_{4}$	$(iii) \text{Distorted octahedral}$
$(d) XeO_{3}$	$(iv) \text{Square pyramidal}$

Code: $(a) \quad (b) \quad (c) \quad (d)$

$XeF_6$ on partial hydrolysis with water produces a compound '$X$'. The same compound '$X$' is formed when $XeF_6$ reacts with silica. The compound '$X$' is
