Question

In $Xe{F}_2,Xe{F}_4$ and $Xe{F}_6\left(g\right)$, the number of lone pairs on $Xe$ are respectively:

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

Answer 1

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

In $Xe{F}_2,Xe{F}_4$ and $Xe{F}_6\left(g\right)$, the number of lone pairs on $Xe$ respectively are $3,2$ and $1$. The number of bond pairs are $2,4$ and $6$ respectively. The total number of valence electrons on $Xe$ are $8$.
