(b) $Xe{O}_3$	(ii) Square planar
(c) $XeO{F}_4$	(iii) Pyramidal
(d) $Xe{F}_4$	(iv) Square pyramidal

• A. (i), (iii), (iv), (ii)
• B. (i), (ii), (iv), (iii)
• C. (iv), (iii), (i), (ii)
• D. (iv), (i), (i), (iii)

Answer 1

Answer: (A)

(i), (iii), (iv), (ii)

In $Xe{F}_6$, the central $Xe$ atom undergoes $s{p}^3{d}^3$ hybridisation and the molecular geometry is distorted octahedral with 1 lone pair and 6 bond pairs of electrons.

In $Xe{O}_3$, the central $Xe$ atom undergoes $s{p}^3$ hybridisation and the molecular geometry is pyramidal with 1 lone pair and 3 bonding domains of electrons.

In $XeO{F}_4$, the central $Xe$ atom undergoes $s{p}^3{d}^2$ hybridization and the molecular geometry is square pyramidal with 1 lone pair and 5 bond pairs of electrons.

In $Xe{F}_4$, the central $Xe$ atom undergoes $s{p}^3{d}^2$ hybridization and the molecular geometry is square planar with 2 lone pairs and 4 bond pairs of electrons.
