Chapter 13, Problem 13.58AP

a.

Interpretation Introduction

Interpretation:

Acceptable name for the below compound has to be given.

Concept Introduction:

IUPAC naming for esters:

Name of the esters are derived from the parent carboxylic acid name.  The alkyl group bonded to the oxygen atom is named first and then followed by the parent carboxylic acid name where the suffix “-ic acid” is replaced by “-ate”.

• Alkyl group, $\text{R'}$ that is bonded to the oxygen atom is named first.
• The $\text{RCO}-$ group is named from the carboxylic acid by changing the suffix “-ic acid” with “-ate”

b.

Interpretation Introduction

Interpretation:

Acceptable name has to be given for the below compound.

Concept Introduction:

Amides contain a nitrogen atom that is bonded to carbonyl group.  The nitrogen atom that is bonded to the carbonyl group may be bonded to alkyl groups or hydrogen atoms.  Depending on the number of carbon atoms that is attached to the nitrogen atom, the amide is classified as primary, secondary, and tertiary.

Naming of amides are done using specific rules:

Primary amides are named by considering the parent carboxylic acid and replacing the “–oic acid” with “–amide”.

Secondary and tertiary amide contains two parts in its name.  The alkyl groups that are bonded to the nitrogen atom is named using N- as the prefix for the alkyl group and this precedes the name.  The $\text{RCO}-$ group is named by the use of –amide as suffix.
