Question

The reaction of $Xe$ and $O _2 F _2$ gives a Xe compound $P$. The number of moles of HF produced by the complete hydrolysis of $1 \,mol$ of $P$ is ______

Answer 1

$\text{Xe} + 2\text{O}_2 + \text{F}_2 \rightarrow \text{XeF}_4 + 2\text{O}_2$
$3\text{XeF}_4 + 6\text{H}_2\text{O} \rightarrow 2\text{Xe} + \text{XeO}_3 + \frac{23}{2}\text{O}_2 + 12\text{HF}$
∴ One mole of $\text{XeF}_4$​ gives 4 moles of HF on hydrolysis.
