XeF _ 6 on partial hydrolysis with water, produces a compound X ....

{XeF}_{6}

on partial hydrolysis with water, produces a compound

X .

The same compound

X

is formed when

{XeF}_{6}

reacts with silica. The compound

X

is:

Options

A ${XeF}_{4}$
B ${XeF}_{2}$
C ${XeO}_{3}$
D ${XeOF}_{4}$

Correct answer

D. ${XeOF}_{4}$

Step-by-step solution

During the hydrolysis the oxidation of xenon not changes in xenon hexafluoride.
$\begin{array}{ll}{XeF}_{6} + {H}_{2}O \to {XeOF}_{4} + 2HF\end{array}$ \left(X\right) $</p><p>$ {SiO}_{2} + 2{XeF}_{6} \to 2{XeOF}_{4} + {SiF}_{4} ( X )$
