Chapter 3.4, Problem 17P

(a)

Interpretation Introduction

Interpretation: To determine the intermolecular force and melting point in ${\text{CH}}_{\text{3}}\text{COOH}$ .

Concept Introduction: The attraction force within the molecule should be used to calculate intermolecular force. Other types of adjacent particles, such as atoms or ions, mediate interactions between molecules. Intermolecular forces, such as electromagnetic forces of attraction as well as repulsion, can act among atoms.

(b)

Interpretation Introduction

Interpretation: To determine the reason for the high melting point of ${\text{CH}}_{\text{3}}\text{COONa}$ as compared to ${\text{CH}}_{\text{3}}\text{COOH}$ .

Concept Introduction: Intermolecular forces strengthen bonds between molecules, and they can affect a compound's melting as well as boiling points. Generally, the melting or boiling temperatures of a substance rise together with the strength and power of the intermolecular interaction.
