Chapter 23, Problem 8STP

a)

Interpretation Introduction

Interpretation: To write the IUPAC names of the given compounds with the molecular formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}\text{O}$ .

Concept Introduction: The compounds are represented in the form of a ball and stick. The balls in this model will represent the atoms in the compound and the stick between the balls will represent the bonds between the atoms.

Answer to Problem 8STP

The given compound is Propan-1-ol.

Explanation of Solution

The carbons atoms in the given model are represented in black color. There are oxygen and hydrogen at the end of the alkyl chain. The presence of the -OH group indicates the alcohol group. There are three carbons in the longest chain along with the -OH group that is attached to the first carbon. Therefore, it is named Propan-1-ol.

Answer to Problem 8STP

The given compound is Methoxy ethane.

Explanation of Solution

In the given compound the longest carbon chain is made up of two carbons which are ethane and the other substituent has only one carbon which is methane. The substituent is named first and then the longest chain with oxy as a prefix. Therefore, the name is Methoxy ethane.
