Question

Which of the following reactions of Xenon compounds are not feasible?
A. \[3Xe{F_4} + 6{H_2}O \to 2Xe + Xe{O_3} + 12HF + 1.5{O_2}\\ \]
B. \[2Xe{F_2} + 2{H_2}O \to 2Xe + 4HF + {O_2}\\ \]
C. \[Xe{F_6} + RbF \to Rb[Xe{F_7}]\\ \]
D. \[Xe{O_3} + 6HF \to Xe{F_6} + 3{H_2}O\\ \]

Answer 1

Hint: Look into the equations carefully. The equation that will be reversible is the answer as the equation will not be feasible.

Complete step by step answer:
Xenon is a chemical element with symbol Xe and atomic number 54. It is a colourless, dense, odourless noble gas found in Earth’s atmosphere in small amounts. Although it is unreactive, xenon can undergo a few chemical reactions such as the formation of Xenon hexafluoroplatinate which is the first noble gas compound to be synthesised. Naturally occurring xenon consists of seven stable isotopes and two long lived radioactive isotopes. More than 40 unstable xenon isotopes undergo radioactive decay. Also, the isotopic ratios of xenon are an important tool for studying the early history of the Solar System.
In the reactions given above, the reaction given in option D is not feasible. The reaction is given as follows:
\[Xe{O_3} \;\; +\;\; 6HF \;\rightleftharpoons \;\;Xe{F_6} \;\; +\;\; 3{H_2}O\]
This reaction is not feasible because the products again react to give the reactants back. This is because xenon fluorides easily undergo hydrolysis and give xenon oxides.

Hence, option D is the correct answer.

Additional Information:
Although xenon is rare and very expensive to extract from Earth’s atmosphere, it has a number of applications. It is used in gas discharge lamps and light emitting devices called flash maps. It is also used as lasers which were discovered in 1962 by bell laboratories. In the medical field, it is used as general anesthesia but is more expensive than conventional anesthesia. It is also used in Neuroprotection, Sports doping, imaging and in surgery. It is also used in various nuclear studies.

Note:
Here the equation is not feasible because it will undergo hydrolysis and give reactants back. Other reactions are not reversible therefore are feasible.
