Question

Assertion :Sodium perxenate $({N a}_{4} X e O_{6})$ reacts with $N a F$ in acidic medium to give $X e O_{3}$ and $F_{2}$ . Reason: $X e O_{6}^{4 -}$ is a stronger oxidant than $F_{2}$ .

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The reaction is as follows:
$+ 8 X e O_{6}^{4 -} + 2^{⊖} + 6 H^{\oplus} ⟶ + 6 X e O_{3} +_{2} + 3 H_{2} O$
The oxidation number of $X e$ decreases from +8 to +6 in $X e O_{3}$ while that of $F$ increases from -1 to zero.
Therefore, $X e O_{6}^{4 -}$ is reduced while $F^{⊖}$ is oxidised.
Hence, $X e O_{6}^{4 -}$ is a stronger oxidant than $F_{2}$ .
