Assertion (A): Sodium perxenate `(Na_(4)XeO_(6))` reacts with `NaF` in acidic medium to give `XeO_(3)` and `F_(2)`
Reason (R ): `XeO_(6)^(4-)` is a stronger oxidant than `F_(2)`.
A. Statement 1 is true, statement 2 is true, statement 2 is a correct explanation for statement 5
B. Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 5
C. Statement 1 is true, statement 2 is false
D. Statement 1 is false, statement 2 is true

  1. Correct Answer – A
    `overset(+8)(XeO_(6)^(4-))+overset(-1)(2F^(ɵ))+6H^(o+) rarr overset(+6)(Xe)O_(3)+overset(0)F_(2)+3H_(2)O`
    The oxidation number of Xe decreases from +8 to +6 in `XeO_(3)` while that of F increase from -1 to zero. Therefore, `XeO_(6)^(4-)` is reduced while `F^(ɵ)` is oxidised.
    Hence, `XeO_(6)^(4-)` is a stronger ocidant than `F_(2)`

Reason (R ): `XeO_(6)^(4-)` is a stronger oxidant than `F_(2)`.
A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct but `(R )` is incorrect.
D. If `(A)` and `(R )` are incorrect.

  1. Correct Answer – A
    Assertion:
    `overset(+8)XeO_(6)^(4-)+overset(-1)(2F^(ө))+6H^(o+)rarroverset(+6)(Xe)O_(3)+overset(0)F_(2)+3H_(2)O`
    Reason: The oxidation number of `Xe` decreases from `+8 “to” +6` in `XeO_(3)` while that of `F` increase from `-1` to zero. Therefore, `XeO_(6)^(4-)` is a stronger oxidant than `F_(2)`.
