What is the total number of lone pairs of electrons on the central atom in $XeOF_4$?

$A$ xenon compound '$A$' upon partial hydrolysis gives $XeO_{2}F_{2}$. The number of lone pairs of electrons present in compound $A$ is ....... . (Round off to the nearest integer)

Which of the following elements has zero valency?

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

Which one of the following is a correct pair with respect to the molecular formula of a xenon compound and the hybridization state of xenon in it?
