Chapter 19, Problem 68AE

Interpretation Introduction

Interpretation:

The reasons for the alkanes having low boiling points has to be given.

Concept Introduction:

Alkanes:

Alkanes are saturated hydrocarbons whose carbon atoms are connected to each other by the carbon-carbon single bonds. The general molecular formula for linear alkanes is ${\text{C}}_n{\text{H}}_{2n+2}$. Here, $n$ indicates the number of carbon atoms in the compound.

Boiling points:

Boiling point is defined as the temperature at which the vapour pressure of the substance at liquid state is exactly equal to the constant external atmospheric pressure above that liquid.
