Chapter E, Problem E.20P

Interpretation Introduction

(a)

Interpretation:

The complete structure is to be drawn, and the IUPAC name is to be provided for the given trivial name.

Concept introduction:

Trivial names of amines consist of the trivial names of the alkyl/aryl groups bonded to nitrogen atom, followed by the functional group name ‘amine’.

The IUPAC name of an amine consists of three parts. The root is the largest alkyl group or the aryl group to which the amine group is attached. The location of the amine group on the root is established by numbering the chain so that it gets the lowest possible number. Any other alkyl/aryl groups bonded to nitrogen is treated as a substituent on the nitrogen. They are listed as prefixes in alphabetical order.

Interpretation Introduction

(b)

Interpretation:

The complete structure is to be drawn and IUPAC name is to be provided for the given trivial name.

Concept introduction:

Trivial names of amines consist of the trivial names of the alkyl/aryl groups bonded to the nitrogen atom, followed by the functional group name ‘amine’.

IUPAC name of an amine consists of three parts. The root is the largest alkyl/aryl group bonded to the nitrogen. The location of the amine group on the root is established by numbering the chain or ring so that it gets the lowest possible number. Any other alkyl/aryl groups bonded to the nitrogen is treated as substituents on the nitrogen atom. They are listed as prefixes in alphabetical order.

Interpretation Introduction

(c)

Interpretation:

The complete structure is to be drawn and IUPAC name is to be provided for $\text{tert-butyldimethylamine}$.

Concept introduction:

Trivial names of amines consist of the trivial names of the alkyl/aryl groups attached to the nitrogen, followed by the functional group name ‘amine’.

The IUPAC name consists of three parts. The suffix is amine. The largest alkyl/aryl group attached to nitrogen determines the root name. Any other alkyl/aryl groups attached to nitrogen is treated as substituent on the nitrogen atom and listed alphabetically as prefixes.

Interpretation Introduction

(d)

Interpretation:

The complete structure is to be drawn and IUPAC name is to be provided for triethylamine.

Concept introduction:

Trivial names of amines consist of the trivial names of the alkyl/aryl groups attached to the nitrogen, followed by the functional group name ‘amine’.

The IUPAC name consists of three parts. The suffix is amine. The largest alkyl/aryl group attached to nitrogen determines the root name. Any other alkyl/aryl groups attached to nitrogen is treated as substituent on nitrogen and listed alphabetically as prefixes.

Interpretation Introduction

(e)

Interpretation:

The complete structure is to be drawn and IUPAC name is to be provided for diphenylamine.

Concept introduction:

Trivial names of amines consist of the trivial names of the alkyl/aryl groups attached to the nitrogen, followed by the functional group name ‘amine’.

The IUPAC name consists of three parts. The suffix is amine. The largest alkyl/aryl group attached to the nitrogen determines the root name. Any other alkyl/aryl groups attached to nitrogen is treated as substituent on nitrogen, and listed alphabetically.
