Chapter 11, Problem 11D.21E

(a)

Interpretation Introduction

Interpretation:

The systematic name of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ has to be provided.

Concept Introduction:

Amines:

Amines are basic chemical derivatives of ammonia in which the bonded hydrogens are replaced by an alkyl or aryl groups.  Amines are classified into,

1. 1) Primary amine: One organic group attached to nitrogen atom.
2. 2) Secondary amine: Two organic groups bonded to nitrogen atom.
3. 3) Tertiary amine: Three organic groups bonded to nitrogen atom.

IUPAC naming of primary amine:

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

Interpretation Introduction

Interpretation:

The systematic name of ${\left({\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\right)}_{\text{2}}\text{NH}$ has to be provided.

2. 2) Secondary amine: Two organic groups bonded to nitrogen atom.
3. 3) Tertiary amine: Three organic groups bonded to nitrogen atom.

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.
