Question

Match List I and List II and select the correct answer using the codes given below in the lists:-
$\begin{array}{cc}\text{List - I (compounds)}& \text{List - II (Shape)}\\ \text{(A)}Xe{F}_4& \text{(P) Tetrahedral}\\ \text{(B)}Xe{O}_3& \text{(Q) Square planar}\\ \text{(C)}Xe{O}_4& \text{(R) Trigonal bipyramidal}\\ \text{(D)}Xe{O}_3{F}_2& \text{(S) Pyramidal}\end{array}$

• A. A-Q; B-R; C-P; D-S
• B. A-Q; B-S; C-P; D-R
• C. A-R; B-Q; C-P; D-S
• D. A-P; B-Q; C-R; D-S

Answer 1

The correct option is B A-Q; B-S; C-P; D-R

$Xe{F}_4=4bondpairs+2lonepairs=s{p}^3{d}^2\to squareplanar$
$Xe{O}_3=3bondpairs+1lonepairs=s{p}^3\to pyramidal$
$Xe{O}_4=4bondpairs=s{p}^3\to Tetrahedral$
$Xe{O}_3{F}_2=5bondpairs\to s{p}^{3}d\to Trigonalbipyramidal$
