Chapter 7.3, Problem 3E

(a)

Interpretation Introduction

Interpretation: The Lewis dot structure for three species of mono atomic bromine needs to be determined.

Concept Introduction:

A Lewis dot structure is representation of an atom with all its valence electrons present as dots in pair around the atomic symbol. The charge on the atom if any is also represented as superscript of the atomic symbol.

(b)

Interpretation Introduction

Interpretation: The curved arrows need to be used to show the flow of electrons. The formation of $\text{B}\text{}{\text{r}}^{+}$ , $\text{B}\text{}{\text{r}}^{-}$ and $\text{B}\text{}{\text{r}}^{•}$ from Br₂ needs to be shown.

(c)

Interpretation Introduction

Interpretation: Whether $\text{B}\text{}{\text{r}}^{+}$ , $\text{B}\text{}{\text{r}}^{-}$ or $\text{B}\text{}{\text{r}}^{•}$ initiates the isomerization of dimethyl maleate to dimethyl fumarate needs to be explained.
