Which of the following compounds does not liberate nitrogen gas on treatment with nitrous acid ?

Options

A. `NO_(2)^(-) (aq) +NH_(4)^(+) overset(Delta)rarr`
B. `CO(NH_(2))_(2)(s)+HNO_(2)("liquid") rarr`
C. `NH_(3)(g)+NaOCI(aq) overset("gelatin" Delta)/("in dilute aq solution")rarr`
D. `NO_(2)^(-)(aq) +Zn(s)+OH^(-)(aq) rarr`

Answer

B

Explanation

`NH_(3)CONH_(2)+HNO_(2)rarrN_(2)+CO_(2)+H_(2)O`,
`NH_(4)NO_(2) overset(Delta)(rarr)N_(2)+H_(2)O`
`NH_(3)+NaOCl underset("indilute aq solution")overset("gelatin", Delta)(rarr)N_(2)H_(4)`
`NO_(2)^(-) underset(Zn)overset(OH^(-))(rarr)NH_(3)`
