Chapter 15.1, Problem 15.4Q

(a)

Interpretation Introduction

Interpretation:

The amine has to be named using systematic and common nomenclature systems.

Concept Introduction:

IUPAC name of primary amine:

• The name of the parent compound has to be determined.
• The –e ending of the alkane chain is replaced with –amine.
• The parent chain is numbered.  The carbon bearing amine group is given the lowest possible number.
• The substituents are named and numbered, and added as prefixes to the alkanamine name.

Common names:

Common names are often used for the simple amines.  The common names of the alkyl groups bonded to the amine nitrogen are followed by the ending –amine.  Each group is listed alphabetically in one continuous word followed by the suffix –amine.

(b)

Interpretation Introduction

Interpretation:

The amine has to be named using systematic and common nomenclature systems.

Concept Introduction:

IUPAC nomenclature of secondary amine:

• The parent compound, that is, the longest alkyl chain is identified.
• The parent compound is named as alkanamine.
• The -alkyl groups are named as $\text{N-}$ alkyl groups, and they are used as prefix in front of the parent alkanamine.

(c)

Interpretation Introduction

Interpretation:

The amine has to be named using systematic and common nomenclature systems.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The amine has to be named using systematic and common nomenclature systems.

Concept Introduction:

IUPAC nomenclature of tertiary amine:

• The parent compound, that is, the longest alkyl chain is identified.
• The parent compound is named as alkanamine.
• The other two-alkyl groups are named as $\text{N-}$ alkyl groups, and they are used as prefix in front of the parent alkanamine.
• If the two alkyl groups are different, they are listed sequentially.
• If the two groups are identical, they are written as $\text{N-}$ dialkyl.
