The nitrogen containing compound produced in the reaction of $HNO_{3}$ with $P_{4}O_{10}$

A) Can also be prepared by reaction of

$P_{4}$ and

$HNO_{3}$

B) is diamagnetic

C) contains one N-N bond

D) reacts with Na metal producing a brown gas

Option B,D

$P_{4}O_{10}$ is a dehydrating agent and converts $HNO_{3}$ into $N_{2}O_{5}$

$2HNO_{3}\rightarrow N_{2}O_{5}+H_{2}O$

$P_{4}O_{10}+6H_{2}O\rightarrow 4H_{3}PO_{4}$

(a) $P_{4}+20HNO_{3}\rightarrow4H_{3}PO_{4}+20NO_{2}+4H_{2}O$

Thus , (a) is incorrect.

(b) $N_{2}O_{5}$ has no unpaired electron and is thus, diamagnetic , (b) is correct

(c)

There is no N-N bond, thus (c) is incorrect

(d) $N_{2}O_{5}+Na\rightarrow NaNO_{3}+NO_{2}$

$N_{2}O_{5}$ vapours of brownish colour. Thus, (d) is correct.
