Which of the following react(s) with $\mathrm{AsF}_{5}$ in liquid $\mathrm{BrF}_{3}$ ?
(a)$\mathrm{XeF_6}$ only
(b)$\mathrm{XeF_6}$ and $\mathrm{XeF_4}$
(c)$\mathrm{XeF_6}$ and $\mathrm{XeF_2}$
(d)$\mathrm{XeF_4}$ and $\mathrm{XeF_2}$
Answer
Answer (as printed): C
Explanation
Separation of $\mathrm{XeF_4}$ from a mixture involves preferential complexation of $\mathrm{XeF_2}$ and $\mathrm{XeF_6}$ and $\mathrm{XeF_4}$ is then removed in vacuum.
