Question

Answer the following.

How are XeO₃ and XeOF₄ prepared?

Answer 1

1) Preparation of XeO₃:

Fluorides of xenon react with water to form XeO₃.

i) \[\ce{\underset{\text{Xenon tetrfluoride}}{3XeF4} + \underset{\text{Water}}{6H2O} -> \underset{\text{Xenon}}{2Xe} + \underset{\text{Xenon trioxide}}{XeO3} + 12HF + 1 \frac{1}{2} O2}\]

ii) \[\ce{\underset{\text{Xenon hexafluoride}}{XeF6} + \underset{\text{Water}}{3H2O} -> \underset{\text{Xenon trioxide}}{XeO3} + 6HF}\]

2) Preparation of XeOF₄:

Partial hydrolysis of XeF₆ yields XeOF₄.

\[\ce{\underset{\text{Xenon hexafluoride}}{XeF6} + \underset{\text{Water}}{H2O} -> \underset{\text{Xenon monooxytetrafluoride}}{XeOF4} + \underset{\text{Hydrogen fluoride}}{2HF}}\]
