Interpretation Introduction

(a)

Interpretation:

The structure corresponding to N-methylaniline is to be drawn.

Concept Introduction:

• Amines are organic compounds which are derived from ammonia by replacing one or more hydrogen atoms of ammonia by the alkyl groups. The amines can be classified as-

1. Primary amines ( ${\text{RNH}}_2$ ) - When one hydrogen of ammonia is replaced by the alkyl or aryl group.
2. Secondary amines ( ${\text{R}}_2\text{NH}$ ) - When two hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.
3. Tertiary amine ( ${\text{R}}_3\text{N}$ ) - When all three hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.

Interpretation Introduction

(b)

Interpretation:

The structure corresponding to m-Ethylaniline is to be drawn.

Concept Introduction:

• Amines are organic compounds which are derived from ammonia by replacing one or more hydrogen atoms of ammonia by the alkyl groups. The amines can be classified as-

1. Primary amines ( ${\text{RNH}}_2$ ) - When one hydrogen of ammonia is replaced by the alkyl or aryl group.
2. Secondary amines ( ${\text{R}}_2\text{NH}$) - When two hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.
3. Tertiary amine ( ${\text{R}}_3\text{N}$) - When all three hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.

Interpretation Introduction

(c)

Interpretation:

The structure corresponding to 3,5-diethylaniline is to be drawn.

Concept Introduction:

• Amines are organic compound which are derived from ammonia by replacing one or more hydrogen atoms of ammonia by the alkyl groups. The amines can be classified as-

2. Secondary amines ( ${\text{R}}_2\text{NH}$ ) - When two hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.
3. Tertiary amine ( ${\text{R}}_3\text{N}$ ) - When all three hydrogen atoms of ammonia are replaced by the alkyl or aryl groups.
