Interpretation Introduction

Interpretation:

Classification of amines with the formula ${\text{C}}_{\text{3}}{\text{H}}_{\text{9}}\text{N}$ as primary, secondary, or tertiary is to be done.

Concept introduction:

The structural formula is a simplified model that represents the arrangement of atoms and bonds in a molecule. Amines are derivative of ammonia obtained by substitution of hydrogen atom attached to the nitrogen atom by an alkyl group. On the basis of the number of alkyl groups, three types of amines are classified as,

1. Primary amines: Amines in which the nitrogen atom is attached to one alkyl group and two hydrogen atoms are called primary amine.

2. Secondary amines: Amines in which the nitrogen atom is attached to two alkyl groups and one hydrogen atom are called secondary amine.

3. Tertiary amines: Amines in which the nitrogen atom is attached to three alkyl groups and zero hydrogen atom are called tertiary amine.

The general name for amines is as follows,

Name of alkyl group + amine
