Upon heating`KClO_(3)` in presence of catalytic amount of `MnO_(2)`, a gas `W` is formed. Excess amount of `W` reacts with white phosphorus to given `X`. The reaction of `X` with pure `HNO_(3)` gives `Y` and `Z`.
Y and Z are, respectively

A

`N_(2)O_(4) " and " HPO_(3)`

B

`N_(2)O_(4) " and " H_(3)PO_(3)`

C

`N_(2)O_(3) " and " H_(3)PO_(4)`

D

`N_(2)O_(5) " and " HPO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
It is the correct answer.
`2KClO_(3) overset((MnO_(2))) underset("heat")to 2KCl+underset((W))(3O_(2))`
`5O_(2)+P_(4) to underset((X))(P_(4)O_(10))`
`P_(4)O_(10) + 4HNO_(3) to underset((Y))(2N_(2)O_(5))+underset((Z))(4HPO_(3))`
