When compound (A) is treated with conc. ...

When compound (A) is treated with conc. `H_(2)SO_(4)`, a reddish brown colour gas (B) is evolved. To this solution, a solution of (C ) is added slowly from the side of the test tube, a blue ring is obtained at the junction of two layers due to formation of (D).
Compound (D) has formula :

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((A))(NaNO_(3))+H_(2)SO_(4) to NaHSO_(4)+HNO_(3)`
`2HNO_(3) to H_(2)O+ underset((B))(2NO_(2))uarr+[O]`
`2C_(6)H_(5)NHC_(6)H_(5)+[O] to (C_(6)H_(5))_(2)underset("blue ring"(D))(N-N(C_(6)H_(5))_(2))+H_(2)O`
This testing also given by various oxidising agent like `CrO_(4)^(2-), Cr_(2)O_(7)^(2-),ClO_(3)^(-)` etc.
