Chapter 4, Problem 4.85P

(a)

Interpretation Introduction

Interpretation:

The oxidation number of bromine in $\text{KBr}$ is to be determined.

Concept introduction:

Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.

The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.

(b)

Interpretation Introduction

Interpretation:

The oxidation number of bromine in ${\text{BrF}}_3$ is to be determined.

Concept introduction:

Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.

The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.

(c)

Interpretation Introduction

Interpretation:

The oxidation number of bromine in ${\text{HBrO}}_3$ is to be determined.

Concept introduction:

Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.

The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.

(d)

Interpretation Introduction

The oxidation number of bromine in ${\text{CBr}}_4$ is to be determined.

Concept introduction:

Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species.

The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
