Question

In $Xe{F}_2,Xe{F}_4\text{and}Xe{F}_5$, the number of lone pairs of $Xe$ is respectively:

• A. $2,3,1$
• B. $1,2,3$
• C. $4,1,2$
• D. $3,2,1$

Answer 1

The correct option is D $3,2,1$

The shape of $Xe{F}_2$ is linear with $3$ lone pairs of electrons.
The shape of $Xe{F}_4$ is Square planar with $2$ lone pairs of electrons.
The shape of $Xe{F}_6$ is Distorted octahedral with $1$ lone pairs of electrons.
