JEE Main levelSingle correct optionDifficulty 2 of 3ph126

$XeF X_{2}$ reacts with the strong fluoride acceptor $SbF X_{5}$ (1:1) to give a salt. The xenon-containing cation is

A $Xe X^{2 +}$
B $XeF X^{+}$
C $XeF X_{3} X^{+}$
D $XeF X_{5} X^{+}$

Answer: B

XeF2 acts as a fluoride donor:

XeF X_{2} + SbF X_{5} [XeF] X^{+} [SbF X_{6}] X^{-}

. Loss of one

F X^{-}

from XeF2 gives

XeF X^{+}

.

XeF X_{3} X^{+}

comes from XeF4 and

XeF X_{5} X^{+}

from XeF6.
