Chapter 8, Problem 8.146AP

(a)

Interpretation Introduction

Interpretation: The three resonating structures of ${\text{O}}_{\text{2}}\text{NNCO}$ for the given arrangement, the assigned formal charge and the structure that contributes most to the bonding in ${\text{O}}_{\text{2}}\text{NNCO}$; the bond that must be broken for the formation of $\text{BrNCO}$ from ${\text{O}}_{\text{2}}\text{NNCO}$ and the other product formed and the Lewis structure of for the given arrangement of nitrogen, carbon and oxygen in ${\text{O}}_{\text{2}}\text{NNCO}$ are to be identified.

Concept introduction: The Lewis symbols of the atoms indicate the total number of valence electrons surrounding the atom or the ions.

Resonance is the process of delocalisation of $\text{π}$ and non bonding electrons in a molecule.

To determine: The three resonating structures of ${\text{O}}_{\text{2}}\text{NNCO}$ for the given arrangement, the assigned formal charge and the structure that contributes most to the bonding in ${\text{O}}_{\text{2}}\text{NNCO}$.

(b)

Interpretation Introduction

To determine: The bond that must be broken for the formation of $\text{BrNCO}$ from ${\text{O}}_{\text{2}}\text{NNCO}$ and the other product formed.

(c)

Interpretation Introduction

To determine: The Lewis structure of for the given arrangement of nitrogen, carbon and oxygen in ${\text{O}}_{\text{2}}\text{NNCO}$.
