Question

$N_2{O}_4$ is a mixed anhydride because it:

• A. Is a mixture of $N_2{O}_3$ and $N_2{O}_5$
• B. Decomposes into two oxides of nitrogen
• C. Reacts with water to give nitric acid
• D. Reacts with water to form two acids

Answer 1

The correct option is D Reacts with water to form two acids

$N_2{O}_4$ reacts with water to form two nitrogen-containing oxyacids.

$\therefore$ $N_2{O}_4$ it is a mixed anhydride.

$N_2{O}_4+H_{2}O\to HN{O}_3+HN{O}_2$
