Chapter 5, Problem 5.20EP

(a)

Interpretation Introduction

Interpretation:

IUPAC name for the carboxylic acid has to be given.

Concept Introduction:

For naming a carboxylic acid in IUPAC nomenclature, the suffix “-oic” is added to the parent alkane name.

IUPAC rules for naming a carboxylic acid:

• The longest parent carbon chain is identified that includes the carboxyl group.
• The parent chain name is changed by replacing the suffix “-e” with “-oic acid”.
• Numbering is done in a way that the carboxyl group is designated as number 1.  This is not indicated in the part of the name because for aldehyde, the carboxyl carbon is always numbered 1.
• The identity and location of substituents if any has to be determined and this information has to be added in front of the IUPAC name.
• If the carboxyl functional group is attached to a ring of carbon atoms, the ring is named and “-carboxylic acid” is added as suffix.
• If the compound contains two carboxyl groups, then suffix “-dioic acid” is added after the parent alkane name.
