Chapter 21, Problem 4STP

Interpretation Introduction

Interpretation:

The type of hydrocarbon that becomes a gas at lowest temperature needs to be determined from the given table.

Concept introduction:

The temperature at which a liquid substance becomes gas is said to be boiling point. At this temperature, the pressure surrounding the liquid and vapor pressure of the liquid becomes equal.

Answer to Problem 4STP

The type of hydrocarbon that becomes a gas at lowest temperature is 1-octene.

Explanation of Solution

Given:

The table:

The type of hydrocarbon that becomes a gas at lowest temperature can be determined from the boiling point given in the table. The given hydrocarbons are of 7 and 8 carbon chain (hept for 7 C and oct for 8 C atoms). From the given data, the hydrocarbon that becomes a gas at lowest temperature is 1-octene as the boiling point of it is lowest that is $\text{-101}{\text{.7 }}^{\text{o}}\text{C}$.
