Question

How many oxides of monomeric nature can nitrogen form?

• A. $1$
• B. $2$
• C. $4$
• D. $5$

Answer 1

The correct option is A $1$

$N$ has 5 valence electron, therefore molecules with $N_2{O}_x$ will have even number of electrons and will be non radical. For monomeric oxide, $N_{2}O$ is the only monomeric nitrogen oxide.

Therefore option A is correct.
