Chapter 23, Problem 37A

a.

Interpretation Introduction

Interpretation: To give the IUPAC names of the given alcohols.

Concept Introduction: The IUPAC nomenclature of alcohols will begin with the selection of the longest carbon chain with an attached hydroxyl group. Number the longest carbon chain in such a way that the hydroxyl group will get the least number. Name the substituent first and then add the longest carbon chain along with the suffix “ol”.

Answer to Problem 37A

  

Explanation of Solution

In the given compound, the longest chain contains three carbons and the hydroxyl group is located on the second carbon. Therefore, it is named Propan-2-ol.

b.

Interpretation Introduction

Interpretation: To give the IUPAC names of the given alcohols.

Concept Introduction: The IUPAC nomenclature of alcohols will begin with the selection of the longest carbon chain with an attached hydroxyl group. Number the longest carbon chain in such a way that the hydroxyl group will get the least number. Name the substituent first and then add the longest carbon chain along with the suffix “ol”.

Answer to Problem 37A

  

Explanation of Solution

In the given compound, the longest chain contains three carbons and the hydroxyl group is located on the first and the second carbon. Therefore, it is named Propan-1,2-diol. Since there are two hydroxyl groups it is named diol.

c.

Interpretation Introduction

Interpretation: To give the IUPAC names of the given alcohols.

Concept Introduction: The IUPAC nomenclature of alcohols will begin with the selection of the longest carbon chain with an attached hydroxyl group. Number the longest carbon chain in such a way that the hydroxyl group will get the least number. Name the substituent first and then add the longest carbon chain along with the suffix “ol”.

Answer to Problem 37A

  

Explanation of Solution

In the given compound, the longest chain contains three carbons and the hydroxyl group is located on the second carbon. Along with the hydroxyl group, there is a methyl group present at the second carbon. Therefore, it is named 2-methylpropan-2-ol.
