"A" obtained by Ostwald's method involving air oxidation of NH 3, upon further air oxidation produces "B". "B" on hydration forms an oxoacid of Nitrogen along with evolution of " A ". The oxoacid also produces "A" and gives positive brown ring test. Identify A and B, respectively.

Question

"A" obtained by Ostwald's method involving air oxidation of NH 3, upon further air oxidation produces "B". "B" on hydration forms an oxoacid of Nitrogen along with evolution of " A ". The oxoacid also produces "A" and gives positive brown ring test. Identify A and B, respectively. (A) NO , NO 2 (B) NO 2, N 2 O 4 (C) N 2 O 3, NO 2 (D) NO 2, N 2 O 5

4 NH 3+5 O 2 xrightarrowΔ underset(A)4 NO +6 H 2 O 2 NO + O 2 longrightarrow underset(B)2 NO 2

$NO, N O_{2}$

$N O_{2}, N_{2} O_{4}$

$N_{2} O_{3}, N O_{2}$

$N O_{2}, N_{2} O_{5}$

$4 N H_{3} + 5 O_{2} Δ (A) 4 NO + 6 H_{2} O$
$2 NO + O_{2} ⟶ (B) 2 N O_{2}$

Q. "A" obtained by Ostwald's method involving air oxidation of NH3​, upon further air oxidation produces "B". "B" on hydration forms an oxoacid of Nitrogen along with evolution of " A ". The oxoacid also produces "A" and gives positive brown ring test. Identify A and B, respectively.
