How are XeO3{\text{Xe}}{{\text{O}}_3} and XeOF4{\text{XeO}}{{\text{F}}_4} prepared? Give the structures.

Explanation

Solution

Xenon is a gas that is used in flash and arc lamps, as well as as a general anaesthetic. The first excimer laser used a xenon dimer molecule as the lasing medium, and the first laser pumps were xenon flash lamps. Xenon is used as a propellant for ion thrusters in satellites and to scan for possible weakly interacting large particles.

Complete answer: The chemical element xenon has the symbol Xe and the atomic number 54. It is a colourless, thick, and odourless noble gas present in trace concentrations in the Earth's atmosphere. Xenon can undergo a few chemical reactions, including the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesised.
In its +6 oxidation state, xenon trioxide is an acidic xenon compound. It's a powerful oxidizer that steadily releases oxygen from water, which is accelerated by exposure to sunlight. When it comes into contact with organic products, it becomes dangerously explosive. It emits xenon and oxygen gas as it detonates.
Fluorides of xenon always react with water vigorously to form XeO3{\text{Xe}}{{\text{O}}_3}
XeF6 Xenon hexafluoride +3H2O Water →XeO3 Xenon trioxide +6HF\mathop {{\text{Xe}}{{\text{F}}_6}}\limits_{{\text{ Xenon hexafluoride }}} + \mathop {3{{\text{H}}_2}{\text{O}}}\limits_{{\text{ Water }}} \to \mathop {{\text{Xe}}{{\text{O}}_3}}\limits_{{\text{ Xenon trioxide }}} + 6{\text{HF}}
3XeF4 Xenon tetrafluoride +6H2O Water →2Xe Xenon +XeO3 Xenon trioxide +12HF+112O2\mathop {3{\text{Xe}}{{\text{F}}_4}}\limits_{{\text{ Xenon tetrafluoride }}} + \mathop {6{{\text{H}}_2}{\text{O}}}\limits_{{\text{ Water }}} \to \mathop {2{\text{Xe}}}\limits_{{\text{ Xenon }}} + \mathop {{\text{Xe}}{{\text{O}}_3}}\limits_{{\text{ Xenon trioxide }}} + 12{\text{HF}} + 1\dfrac{1}{2}{{\text{O}}_2}

Sometimes Partial hydrolysis of XeF6{\text{Xe}}{{\text{F}}_6} yields XeOF4{\text{XeO}}{{\text{F}}_4}
The chemical compound xenon oxytetrafluoride is an inorganic compound. It's a colourless, solid liquid with a melting point of −46.2oC-46.2^oC that's made by partially hydrolyzing XeF6Xe{F_6}.
XeF6 Xenon hexafluoride +H2O Water →XeOF4 Xenon oxytetrafluoride +2HF Hydrogen fluoride \mathop {{\text{Xe}}{{\text{F}}_6}}\limits_{{\text{ Xenon hexafluoride }}} + \mathop {{{\text{H}}_2}{\text{O}}}\limits_{{\text{ Water }}} \to \mathop {{\text{XeO}}{{\text{F}}_4}}\limits_{{\text{ Xenon oxytetrafluoride }}} + \mathop {2{\text{HF}}}\limits_{{\text{ Hydrogen fluoride }}}

Note:
Seven stable isotopes and two long-lived radioactive isotopes make up naturally occurring xenon. More than 40 unstable xenon isotopes decay radioactively, and xenon isotope ratios are a useful instrument for researching the Solar System's early history. The most important (and unwanted) neutron absorber in nuclear reactors is radioactive xenon-135, which is formed by beta decay from iodine-135 (a result of nuclear fission).
