i.(A)underset(Delta)overset(NaOH)rarr(B)...

i.(A)`underset(Delta)overset(NaOH)rarr(B)(g) overset(HCI)rarr` While fumes.
ii. After (B) is expelled completely, resultant alkline solution again gives gas (B) on heating with zine
iii.(A) `overset(Delta)rarr N_(2)O +H_(2)O`
Identify B

A

`SO_(2)`

B

`NH_(3)`

C

`N_(2)O`

D

`NO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
By (iii) (A) gives `N_(2)O + 2H_(2)O` on hence (A) is `NH_(4)NO_(3)`
`NH_(4)NO_(3) overset(Delta) to N_(2) O + 2H_(2)O`
i. `NH_(4)NO_(3) + NaOH overset(Delta) to NaNO_(3) `+ `overset(NH_(3))underset((B)) + H_(2)O`
`NH_(3) + HCI rarr overset(NH_(4)CI)underset("white famus") + H_(2)O`
iii`2NaOH + Zn overset(Delta to Na_(2)ZnO_(2) + 2H`
`NaNO_(3) + KH overset(Delta)to NaOH + overset(NH_(3))underset((B)) + 2H_(2)O`
`(NH_(2)` gas in obtain due to reeduction of `NO_(3)^(Theta))`
