Question

In addition to those in Table 14.3, other less stable nitrogen oxides exist. Draw a Lewis structure for each of the following:

(a) ${\mathbf{\text{N}}}_{\mathbf{\text{2}}}{\mathbf{\text{O}}}_{\mathbf{\text{2}}}$, a dimer of nitrogen monoxide with an $\mathbf{\text{N-N}}$bond.

(b) ${\mathbf{\text{N}}}_{\mathbf{\text{2}}}{\mathbf{\text{O}}}_{\mathbf{\text{2}}}$, a dimer of nitrogen monoxide with no $\mathbf{\text{N-N}}$bond.

(c) ${\mathbf{\text{N}}}_{\mathbf{\text{2}}}{\mathbf{\text{O}}}_{\mathbf{\text{3}}}$with no $\mathbf{\text{N-N}}$bond.

(d) ${\mathbf{\text{NO}}}^{\mathbf{+}}$ and ${{\mathbf{\text{NO}}}_{\mathbf{\text{3}}}}^{\mathbf{-}}$ , products of the ionization of liquid ${\mathbf{N}}_2{\mathbf{O}}_4$.

Short answer

(d)

Step-by-step solution

Lewis structure:

Compounds' Lewis structures reveal details on the molecule's structure, the types of atom-atom bonds present, and the number of lone pairs in the atoms. Dots are used to depict each atom's valence electrons or lone pairs.

(a) Lewis structure of N2O2:

The Lewis structure of ${\text{N}}_{\text{2}}{\text{O}}_{\text{2}}$, a dimer of nitrogen monoxide with an $\text{N-N}$ bond is given below.

(b) Lewis structure of N2O2: 

The Lewis structure of ${\text{N}}_{\text{2}}{\text{O}}_{\text{2}}$, a dimer of nitrogen monoxide with no $\text{N-N}$ bond is given below.

(c) Lewis structure of  N2O3:

The Lewis structure of ${\text{N}}_{\text{2}}{\text{O}}_{\text{3}}$, a dimer of nitrogen monoxide with no $\text{N-N}$bond is given below.

Lewis structure of  NO+ and  NO3−:

The Lewis structure of ${\text{NO}}^{+}$and ${{\text{NO}}_{\text{3}}}^{-}$, a dimer of nitrogen monoxide with no $\text{N-N}$bond is given below.
