Which one of the following oxides of nitrogen is known as ‘anhydride’ of nitric acid?

A
$\mathrm{N}_2 \mathrm{O}$
B
$\mathrm{N}_2 \mathrm{O}_3$
C
$\mathrm{NO}_2$
Correct answer
D
$\mathrm{N}_2 \mathrm{O}_5$

Solution

Two oxides of nitrogen are acid anhydrides; that is, they react with water to form nitrogen-containing oxyacids. Dinitrogen trioxide is the anhydride of nitrous acid, HNO 2 , and dinitrogen pentoxide is the anhydride of nitric acid, HNO 3.

Hence, the correct answer is option: 'D'.
