Question

In $Xe{O}_2{F}_2,XeO{F}_4,Xe{F}_4,Xe{F}_6$ the number of lone pair on $Xe$ is respectively

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

Answer 1

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

Central atom (Xe) in $Xe{O}_2{F}_2$ contains one lone pair of electron.
Central atom (Xe) in $XeO{F}_4$ contains one lone pair of electron.
Central atom (Xe) in $Xe{F}_4$ contains two lone pair of electron.
Central atom (Xe) in $Xe{F}_6$ had distorted octahedron shape and it contains one lone pair of electron.
Thus option (d) is correct.
