Under ambient condition , the total number of gases released products in the final step of the reaction scheme shown below is

Options

A. 0
B. 1
C. 2
D. 3

Answer

C

Explanation

`XF_(6) + 3H_(2)O underset("hydrolysis")overset("Complete")rarr underset(P)(XeO_(3)) + 6 HF`

`underset(Q)(2 HXeO_(4)^(-)) 2OH^(-) underset(("Slow disproportionation"))overset(OH^(-)//H_(2)O)rarr Xe(g) + XeO_(6)^(4-) (aq) + 2H_(2)O (l) + O_(2)(g)`
Two gases, i.e., Xe and `O_(2)` are released, i.e., option (c) is correct.
