Question

Copper metal on treatemet with dilute `HNO_(3)` produces a gas X,X when passed through acidic solution of stannous chloride, a nitrogen containing compound Y is obtained. Y on reaction with nitrous acid produces a gas Z. Then
A. `Z = NO`
B. `Y = N_(2)O_(3)`
C. `Y= NH_(2)OH`
D. `Z = N_(2)O`

Answer 1

Correct Answer - A::C::D
`Cu + dil HNO_(3) +NO + Cu(NO_(3))_(2) +H_(2)O`
`NO +HCI +SnCI_(2) rarr SnCI_(4) + NH_(2)OH`
`NH_(2)OH +HCI rarr N_(2)O +H_(2)O`
`X = NO, Y = NH_(2)OH, Z = N_(2)O`
