Y' is obtained by the decomposition of a substance 'X'. Oxygen present in 'X' is univalent. 'Y' reacts with a neutral oxide and evolves 'Z' which is composed of reddish brown fumes which turns moist blue litmus red. Identify 'X', 'Y' and 'Z'.

A

`H_(2)O_(2),H_(2)" and "CO_(2)`

B

`H_(2)O_(2),O_(2)" and "NO_(2)`

C

`KCIO_(3),CI_(2)" and "O_(2)`

D

`HgO, O_(2)" and "NO`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset((X))(H_(2))O_(2)toH_(2)O_(2)+underset((Y))(O_(2))`
`NO+underset((Y))(O_(2))tounderset(("reddish brown"))underset((Z))(NO_(2))`
`O_(2)` (Y) is neutral towards litmus whlile `NO_(2)` is acidic and hence turns moist blue to red.
