Chapter F, Problem F.19P

Interpretation Introduction

(a)

Interpretation:

The structure of $\text{5-phenylpentanamide }$ is to be drawn.

Concept introduction:

The structure of an amide can be drawn on the basis of its IUPAC name. The name consists of a root name indicating the longest continuous carbon chain that includes the carbonyl carbon of the amide group. Any prefixes present indicate the substituents on the alkyl chain or on the nitrogen if the locant is ‘N’.

If the amide contains a chiral center, the absolute configuration, R or S, is shown at the start, along with its locant.

Interpretation Introduction

(b)

Interpretation:

The structure of $\text{(2S, 3S)-2, 3-dimethoxyhexanediamide}$ is to be drawn.

Concept introduction:

The structure of an amide can be drawn on the basis of its IUPAC name. The name consists of a root name indicating the longest continuous carbon chain that includes the carbonyl carbon of the amide group. Any prefixes present indicate the substituents on the alkyl chain or on the nitrogen if the locant is ‘N’.

If the amide contains a chiral center, the absolute configuration, R or S, is shown at the start, along with its locant.

Interpretation Introduction

(c)

Interpretation:

The structure of $\text{N-phenylcyclobutanecarboxamide}$ is to be drawn.

Concept introduction:

The structure of an amide can be drawn on the basis of its IUPAC name. The name consists of a root name indicating the longest continuous carbon chain that includes the carbonyl carbon of the amide group. Any prefixes present indicate the substituents on the alkyl chain or on the nitrogen if the locant is ‘N’.

If the amide contains a chiral center, the absolute configuration, R or S, is shown at the start, along with its locant.
