Chapter 16, Problem 16.6E

Interpretation Introduction

Interpretation:

The structural formulas of the four amines that have the molecular formula ${\text{C}}_3{\text{H}}_{\text{9}}\text{N}$ are to be drawn. The amines are to be labeled as primary, secondary or tertiary amine.

Concept introduction:

Amines are nitrogen-containing organic compounds. The general formula of amines is $\text{R}-{\text{NH}}_{\text{2}}$. Amines can be classified as primary amine, secondary amine, and tertiary amine.

In primary amines, one of the hydrogen atoms of ammonia is replaced by alkyl or aryl group.

In secondary amines, two of the hydrogen atoms of ammonia are replaced by alkyl or aryl group.

In tertiary amines, all hydrogen atoms of ammonia are replaced by alkyl or aryl group.
