Chapter 18, Problem 38P

Interpretation Introduction

(a)

Interpretation:

The structure of cyclobutylamine needs to be determined.

Concept Introduction:

The name of the amines is written based on their structure that whether they are primary, secondary or tertiary. The name of the primary amine is written using the longest carbon chain having the amine group. At the end of the name of the parent alkane chain, the suffix amine is added.

In the case of secondary and tertiary amines, if there are more than 1 same alkyl groups present, they are named using prefix di- or tri- along with the primary amine name. If there is more than one type of alkyl groups, they are named as N-substituted primary amines.

Interpretation Introduction

(b)

Interpretation:

The structure of4-nonanamine needs to be determined.

Concept Introduction:

The name of the amines is written based on their structure that whether they are primary, secondary or tertiary. The name of the primary amine is written using the longest carbon chain having the amine group. At the end of the name of the parent alkane chain, the suffix amine is added.

In the case of secondary and tertiary amines, if there are more than 1 same alkyl groups present, they are named using prefix di- or tri- along with the primary amine name. If there is more than one type of alkyl groups, they are named as N-substituted primary amines.

Interpretation Introduction

(c)

Interpretation:

The structure of N-pentylaniline needs to be determined.

Concept Introduction:

The name of the amines is written based on their structure that whether they are primary, secondary or tertiary. The name of the primary amine is written using the longest carbon chain having the amine group. At the end of the name of the parent alkane chain, the suffix amine is added.

In the case of secondary and tertiary amines, if there are more than 1 same alkyl groups present, they are named using prefix di- or tri- along with the primary amine name. If there is more than one type of alkyl groups, they are named as N-substituted primary amines.

Interpretation Introduction

(d)

Interpretation:

The structure of3-amino-2-butanone needs to be determined.

Concept Introduction:

The name of the amines is written based on their structure that whether they are primary, secondary or tertiary. The name of the primary amine is written using the longest carbon chain having the amine group. At the end of the name of the parent alkane chain, the suffix amine is added.

In the case of secondary and tertiary amines, if there are more than 1 same alkyl groups present, they are named using prefix di- or tri- along with the primary amine name. If there is more than one type of alkyl groups, they are named as N-substituted primary amines.

Interpretation Introduction

(e)

Interpretation:

The structure of3-methyl-1-butanamine needs to be determined.

Concept Introduction:

The name of the amines is written based on their structure that whether they are primary, secondary or tertiary. The name of the primary amine is written using the longest carbon chain having the amine group. At the end of the name of the parent alkane chain, the suffix amine is added.

In the case of secondary and tertiary amines, if there are more than 1 same alkyl groups present, they are named using prefix di- or tri- along with the primary amine name. If there is more than one type of alkyl groups, they are named as N-substituted primary amines.

Interpretation Introduction
