Question

Which of the following reactions are correct with respect to the formation of products? I. \[ \mathrm{XeF_6+NaF\rightarrow Na[XeF_7]} \] II. \[ \mathrm{XeF_2+PF_5\rightarrow [XeF]^+[PF_6]^-} \] III. \[ \mathrm{XeF_4+SbF_5\rightarrow [XeF_3]^+[SbF_6]^-} \] The correct answer is

• A. II, III only
• B. I, III only
• C. I, II only
• D. I, II, III

Hint:

Strong Lewis acids such as \[ \boxed{\mathrm{PF_5}\ \text{and}\ \mathrm{SbF_5}} \] abstract fluoride ions from xenon fluorides, producing ionic xenon fluorides.

Answer 1

The Correct Option is D
