Question

Complete hydrolysis of $Xe{F}_4$ and $Xe{F}_6$ gives its oxides $P$ and $Q$, respectively. Identify $P$ and $Q$

• A.
• B.
• C.
• D. ****

Answer 1

Answer: (C)

The complete hydrolysis of $Xe{F}_4$ and $Xe{F}_6$ produces $Xe{O}_3$ which is xenon trioxide. This xenon trioxide is highly explosive and acts as a powerful oxidising agent in solution.
Complete hydrolysis of $Xe{F}_4$
$\underset{\text{ Xenon tetrafluoride }}{6Xe{F}_4}+12H_{2}O\to \underset{\text{ Xenon }}{4Xe}+\underset{\text{ Xenon trioxide }(P)}{2Xe{O}_3}\underset{\text{ Hydrogen fluoride }}{24HF}+3O_2$
$Xe{F}_4$ on partial hydrolysis produces $XeO{F}_2$ (xenon oxyfluoride).
Complete hydrolysis of $Xe{F}_6$
$Xe{F}_6$ is one of 3 binary fluoride formed by the xenon. $Xe{O}_3$ is highly explosive and acts as a powerful oxidising agent in solution.
$\underset{\text{ Xenon hexafluoride }}{Xe{F}_6}+3H_{2}O\to \underset{\text{ Xenon trioxide }(Q)}{Xe{O}_3}+\underset{\text{ Hydrogen }}{6HF}$
