A dark voilent solid X reacts with NH(3)...

A dark voilent solid X reacts with `NH_(3)` to form a mild explosive Y which decomposes to give a voilet coloured gas. X also reacts with `H_(2)` to give an acid Z. Z can also be prepared by heating its salt with `H_(3) PO_(4)`
The dark violent solid X is

A

HCl

B

HI

C

HBr

D

`H_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
`2NH_(3) + underset("(X)")(3I_(2)) rarr NI_(3). underset("(Y)")NH_(3)+3HI , underset("(X)")(I_(2)) + H_(2) rarr underset("(Z)")(2HI)`
