Question

The compound in which the number of $d\pi -p\pi$ bonds are equal to those present in ${Cl{O}_4}^{-}$ is:

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

Answer 1

Answer: (B)

$Xe{O}_3$

$Cl{O}_4^{-}$ contains 3 $d\pi -p\pi$ bonds in its molecule. $Xe{O}_3$ also contain 3 $d\pi -p\pi$ bonds as shown in figure. Here formation of $\pi$ bond takes place between d orbital electrons of Xe and p orbital electrons of oxygen.
