Question

Which of the following statements regarding nitrogen sesquioxide is not correct?

• A. Nitrogen sesquioxide is stable only in the liquid state. It dissociated in the vapour phase
• B. Dinitrogen sesquioxide is a neutral oxide
• C. Dinitrogen sesquioxide contains a weak $N-N$ bond
• D. Dinitrogen sesquioxide exists in two different crystalline forms

Answer 1

The correct option is B Dinitrogen sesquioxide is a neutral oxide

Nitrogen sesquioxide or dinitrogen trioxide $\left(N_2{O}_3\right)$ is an acidic oxide. It is an anhydride of nitrous acid and dissolves in water to form $HN{O}_2$, an unstable acid.

$N_2{O}_3+H_{2}O\to 2HN{O}_2$
