Question

The nitrogen oxide(s) that contain(s) $N-N$ bonds is/are:

• A. $N_{2}O$
• B. $N_2{O}_3$
• C. $N_2{O}_4$
• D. $N_2{O}_5$

Answer 1

Answer: (A), (B), (C)

The correct options are
A $N_2{O}_3$
B $N_{2}O$
C $N_2{O}_4$

$A.N\equiv N\to O\Rightarrow N_{2}O$

$B.O=N-N=O\Rightarrow N_2{O}_3$

$\downarrow$

$O$

$C.O=N-N=O\Rightarrow N_2{O}_4$

$\downarrow$ $\downarrow$

$O$ $O$

$D.O=N-O-N=O\Rightarrow N_2{O}_5$

$\downarrow$ $\downarrow$

$O$ $O$

From the above structure of the compounds, it is clear option A, B and C are correct.
