JEE Main levelSingle correct optionDifficulty 2 of 3ph125

$XeF X_{6}$ reacts with CsF to give $Cs [XeF X_{7}]$ . In this reaction $XeF X_{6}$ behaves as

Aa fluoride ion acceptor (Lewis acid)
Ba reducing agent that oxidises $F X^{-}$ to $F X_{2}$
Ca fluoride ion donor (Lewis base)
Dan oxidising agent that oxidises $Cs X^{+}$

Answer: A

XeF X_{6} + F X^{-} [XeF X_{7}] X^{-}

: the Xe compound accepts

F X^{-}

from CsF, so it is a Lewis acid. No oxidation state changes (Xe stays +6, F stays

- 1

).
