The noble gas which forms the maximum number of compounds is

Which of the following statements is $NOT$ correct?

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

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

Noble gases do not react with other elements because.......

Consider the following transformations:
$I. XeF_6 + NaF \to Na^+[XeF_7]^-$
$II. 2PCl_{5(s)} \to [PCl_4]^+[PCl_6]^-$
$III. [Al(H_2O)_6]^{3+} + H_2O \to [Al(H_2O)_5OH]^{2+} + H_3O^+$
Which of the above transformations are correct?
