Chapter 7, Problem 7.9PP

(a)

Summary Introduction

To explain:

Type of attractive force formed in between molecule $\text{NaF}$(sodium fluoride).

Introduction:

London forces include the forces which are temporarily formed between non-polar hydrocarbon molecules as a result of formation of electron cloud of atoms.

Dipole-dipole interactions are formed between molecules due to formation of partial positive and negative charges on atoms due to their electronegativity differences.

Ion-dipole interactions are formed between polar molecules like water which contain partial functional groups and charged functional groups or between small electronegative atoms.

Ionic interactions are formed between positively charged cation and a negatively charged anion.

(b)

Summary Introduction

To explain:

Type of attractive force formed in between molecule ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$ (propane).
