The reaction of $\mathrm{XeF_6}$ with a limited amount of quartz gives compound A. Then on reaction with an equivalent amount of $\mathrm{XeO_3}$. A gives B. The products A and B are, respectively
(a)$\mathrm{XeOF_2}$ and $\mathrm{XeO_2F_2}$
(b)$\mathrm{XeOF}_{4}$ and $\mathrm{XeO}_{2} \mathrm{F}_{2}$
(c)$\mathrm{XeOF_2}$ and $\mathrm{XeOF_4}$
(d)$\mathrm{XeO}_{2} \mathrm{F}_{2}$ and $\mathrm{XeOF}_{4}$
Answer
Answer (as printed): B
Explanation
\[ 2\mathrm{XeF_6} + \mathrm{SiO_2}\,(\text{quartz}) \rightarrow 2\mathrm{XeOF_4}\,(A) + \mathrm{SiF_4} \]
\[ \mathrm{XeOF_4}\,(A) + \mathrm{XeO_3} \rightarrow \mathrm{XeO_2F_2}\,(B) \]
