Answer to Problem 14.140EP

IUPAC name for the given compound is 2-hexanol.

Explanation of Solution

Given structure of compound is shown below,

General, Organic, and Biological Chemistry Seventh Edition, Chapter 14, Problem 14.140EP , additional homework tip 4

The longest continuous carbon chain with the hydroxyl group is found to be six carbon chain. Therefore, the parent alkane is hexane. As a hydroxyl group is present the name of the alcohol can be given as hexanol.

General, Organic, and Biological Chemistry Seventh Edition, Chapter 14, Problem 14.140EP , additional homework tip 5

The numbering has to be given so that the hydroxyl group gets the least numbering. In this case, the hydroxyl group is present in the second carbon atom. Therefore, the IUPAC name can be given as 2-hexanol.

General, Organic, and Biological Chemistry Seventh Edition, Chapter 14, Problem 14.140EP , additional homework tip 10

First step is to identify the longest continuous carbon chain. In the given structure, it is found that the longest carbon chain is four carbon chain. Hence, the parent alkane is butane.

The suffix -thiol is added to the parent alkane name. This gives the name as butanethiol.

Next step is to number the carbon atoms so that the thiol functional group gets the least numbering. In this case, it is in first carbon atom. Methyl group is present as substituent in the second carbon atom. Therefore, the IUPAC name of the given compound is 2-methyl-1-butanethiol.

Conclusion

IUPAC name for the given compound is assigned.

Answer 31

(d)

Interpretation Introduction

Interpretation:

IUPAC name for the given compound has to be assigned.

Concept Introduction:

IUPAC rules for naming thioalcohols that contain single thiol group:

• Longest carbon chain has to be identified that contains thiol group also. The chain name is obtained by adding the suffix “-thiol”. If the compound contains an unsaturated bond, then the respective name has to be changed with regard to alkane.

• The numbering has to be given so that the thiol group gets the least numbering.

• Name and location of any other substituent present in the chain has to be identified.

• If in a ring the thiol group is present, then that carbon is numbered 1 and the numbering then proceeds counterclockwise or clockwise in a way that substituents present if any gets the least numbering.

IUPAC rules for naming thioalcohols that contain more than one thiol group:

• The same rules said above is followed but the prefix di-, tri-, tetra etc is added corresponding to the number of thiol groups that is present.
