Chapter 11, Problem 11.23SP
Interpretation Introduction

(a)

Interpretation:

Whether hexane or 1-hexanol has high viscosity should be determined.

Concept introduction:

Intermolecular forces determine the properties of liquid and solid. The attractive forces that occur in all types of particle-like molecules, ions, and atoms are called intermolecular forces.

Types of intermolecular forces are London dispersion forces, hydrogen bonding, and ion-dipole forces.

The most important properties of liquids are viscosity and surface tension.

The measure that resists liquid flow is called viscosity. Viscosity is the ease by which each molecule of the liquid can move. Viscosity and intermolecular forces are proportional to each other. Low viscosity is due to weak intermolecular force in the molecule. On the other hand, strong intermolecular force in a molecule causes high viscosity.

The measure that resists liquid from spread out and increases the surface area is called surface tension. The difference in intermolecular forces in molecules at the surface of the liquid and in its interior causes surface tension.
