Chapter 22, Problem 51QAP

Interpretation Introduction

(a)

Interpretation:

The expected bond angle of ${\text{CH}}_{\text{3}}{\text{-CH}}_{\text{3}}$ from the following should be determined:

$\text{109}{\text{.5}}^{\text{o}}$; ${\text{120}}^{\text{o}}$; ${\text{180}}^{\text{o}}$.

Concept introduction:

The angle formed between two bonds originating from the same atom in a covalent compound is said to be the bond angle.

Interpretation Introduction

(b)

Interpretation:

The expected bond angle of ${\text{CH}}_{\text{3}}{\text{-CH=CH}}_2$ from the following should be determined:

$\text{109}{\text{.5}}^{\text{o}}$; ${\text{120}}^{\text{o}}$; ${\text{180}}^{\text{o}}$.

Concept introduction:

The angle formed between two bonds originating from the same atom in a covalent compound is said to be the bond angle.

Interpretation Introduction

(c)

Interpretation:

The expected bond angle of ${\text{CH}}_{\text{3}}\text{-C}\equiv {\text{C-CH}}_{\text{3}}$ from the following should be determined:

$\text{109}{\text{.5}}^{\text{o}}$; ${\text{120}}^{\text{o}}$; ${\text{180}}^{\text{o}}$.

Concept introduction:

The angle formed between two bonds originating from the same atom in a covalent compound is said to be the bond angle.
