Question

Which of the following reactions of Xenon compounds is not feasible?

• A. $XeO_{3}+6HF \rightarrow XeF_{6}+3H_{2}O$
• B. $3XeF_{4}+6H_{2}O \rightarrow 2Xe+XeO_{3}+12HF+1.5O_{2}$
• C. $2XeF_{2}+2H_{2}O \rightarrow 2Xe+4HF+O_{2}$
• D. $XeF_{6}+RbF \rightarrow Rb\left[XeF_{7}\right]$

Answer 1

Answer: (A)

$XeO_{3}+6HF \rightarrow XeF_{6}+3H_{2}O$
Above reaction is not feasible because $XeF_{6}$ formed will further produce $XeO_{3}$ by getting hydrolysed.
$XeF_{6}+H_{2}O \rightarrow XeOF_{4}+2HF$
$XeOF_{4}+H_{2}O \rightarrow XeO_{2}F_{2}+2HF$
$XeO_{2}F_{2}+H_{2}O \rightarrow XeO_{3}+2HF$
