Question

In which of the following pairs of compounds xenon is involved in $s{p}^3$ hybridisation :

• A. $Xe{F}_2,Xe{F}_4$
• B. $Xe{F}_2,Xe{F}_6$
• C. $Xe{F}_4,Xe{F}_6$
• D. $Xe{O}_3,Xe{O}_4$

Answer 1

The correct option is D $Xe{O}_3,Xe{O}_4$

$Xe{O}_3=3+\frac{8-6}{2}=3+1$ $s{p}^3$ hybridisation is trigonal pyramidal with asymmetric charge distribution on the central atom. Therefore this molecule is polar.

$Xe{O}_4=4$ $s{p}^3$ hybridisation In the fourth excited, xenon atom has 8 unpaired electrons. One “s” and three “p” – orbitals undergo $s{p}^3$ hybridisation.
