Q105P - Chemistry: Molecular Nature Of Matter And Change

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  ${\mathbf{N}}_2{\mathbf{O}}_4$.

Step-by-Step Solution

The answer is as follow.

(a) 

(b) 

(c) 

(d)

Step 1: 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 N 2 O 2 :

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 N 2 O 2 :

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 N 2 O 3 :

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 NO 3 − :

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.
