Chapter 8, Problem 8.13P

Interpretation Introduction

(a)

Interpretation:

Among acetaldehyde and propene, the one that has the higher boiling point is to be predicted.

Concept introduction:

The boiling point is defined as a temperature at which the conversion of a liquid into a vapor state takes place. At this temperature, the liquid’s vapor pressure becomes equal to the external pressure surrounding the liquid. The boiling point of a molecule depends upon the interactions that result from permanent or induced dipoles.

The dipole moment is defined as the charge separation between two atoms in a covalent bond or between two ions in an ionic bond. It is used to determine the polarity of atoms or ions.

Interpretation Introduction

(b)

Interpretation:

The location of the curve for aldehyde boiling points in the given Figure is to be identified.
