Solution

The correct option is C $H_{2} N_{2} O_{2}$
$N_{2} O$ is formed when $H_{2} N_{2} O_{2}$ is reacted with $P_{2} O_{5}$ . the $N_{2} O$ is soluble in water and gives the $H_{2} N_{2} O_{2}$
$N_{2} O (g) + H_{2} O (l) \to H_{2} N_{2} O_{2}$
$H_{2} N_{2} O_{2}$ , or hyponitrous acid, is an isomer of nitroamine/nitroamide, a known explosive.
