The nitrogen containing compound produced in the reaction of H N O 3 with P 4 O 10

1. Can also be prepared by reaction of ${\mathrm{P}}_4$ and $\mathrm{H}\mathrm{N}{\mathrm{O}}_3$
2. Is diamagnetic
3. Contains one N-N bond
4. Reacts with Na metal producing a brown gas

Solution

${\mathrm{P}}_4{\mathrm{O}}_{10}+4\mathrm{H}\mathrm{N}{\mathrm{O}}_3\stackrel{\mathrm{d}\mathrm{e}\mathrm{h}\mathrm{y}\mathrm{d}\mathrm{r}\mathrm{a}\mathrm{t}\mathrm{i}\mathrm{o}\mathrm{n}\mathrm{ }\mathrm{H}\mathrm{N}{\mathrm{O}}_3}{\to }4\left(\mathrm{H}\mathrm{P}{\mathrm{O}}_3\right)+2{\mathrm{N}}_2{\mathrm{O}}_5\left(\mathrm{r}\mathrm{e}\mathrm{q}\mathrm{u}\mathrm{i}\mathrm{r}\mathrm{e}\mathrm{d}\mathrm{ }\mathrm{p}\mathrm{r}\mathrm{o}\mathrm{d}\mathrm{u}\mathrm{c}\mathrm{t}\right)$
A] ${\mathrm{P}}_4+20\mathrm{H}\mathrm{N}{\mathrm{O}}_3\to 4{\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_4+20\mathrm{N}{\mathrm{O}}_2\uparrow +4{\mathrm{H}}_2\mathrm{O}$
B] ${\mathrm{N}}_2{\mathrm{O}}_5$ is diamagnetic in nature
C]
${\mathrm{N}}_2{\mathrm{O}}_5$ contains one N - O - N bond not N - N bond.
D] $\mathrm{N}\mathrm{a}+{\mathrm{N}}_2{\mathrm{O}}_5\to \mathrm{N}\mathrm{a}\mathrm{N}{\mathrm{O}}_3+\mathrm{N}{\mathrm{O}}_2\uparrow \left(\mathrm{b}\mathrm{r}\mathrm{o}\mathrm{w}\mathrm{n}\mathrm{ }\mathrm{g}\mathrm{a}\mathrm{s}\right)$
