What will be the

{A}

and

{B}

in the following equations.

\begin{gathered} 8{{N}}{{{H}}_3} + \mathop {3{{C}}{{{l}}_2}}\limits_{(A)} \to 6{{N}}{{\text{H}}_4}{{Cl}} + {{{N}}_2} \quad \\ {{N}}{{{H}}_3} + \mathop {3{{C}}{{{l}}_2}}\limits_{(B)} \to {{NC}}{{{l}}_3} + 3{{HCl}} \quad \\ \end{gathered}

View answer and explanation

Correct option: A

{A}=

Excess,

{B}=

Excess

Option B (

\mathrm{N}_2 \mathrm{O}_5

) is correct because when N₂O₅ is hydrolyzed, it forms only HNO₃, where nitrogen remains in the +5 oxidation state, thus no disproportionation occurs.
