Chapter 13, Problem 13.63AP

a.

Interpretation Introduction

Interpretation:

Amine given has to be named.

Concept Introduction:

Amines are compounds that contains carbon atom bonded to nitrogen in ammonia by replacing one or more hydrogen atoms.  IUPAC naming for amine compounds follows simple rules.

• In case of primary amine, to the nitrogen atom, one alkyl group is bonded.  The name of the alkyl group is written followed by suffix –amine resulting in a single word.
• In case of secondary and tertiary amine, the different alkyl groups are named as in case of primary amine but arranged in alphabetical order.  If there are identical alkyl groups attached to nitrogen atom, then suitable prefix di- or tri- is used.

Interpretation Introduction

Interpretation:

Acceptable name has to be given for the below compound.

${\text{CH}}_{\text{3}}{{\text{(CH}}_{\text{2}}\text{)}}_{\text{4}}{\text{CONH}}_{\text{2}}$

Concept Introduction:

Amides contain a nitrogen atom that is bonded to carbonyl group.  The nitrogen atom that is bonded to the carbonyl group may be bonded to alkyl groups or hydrogen atoms.  Depending on the number of carbon atoms that is attached to the nitrogen atom, the amide is classified as primary, secondary, and tertiary.

Naming of amides are done using specific rules:

Primary amides are named by considering the parent carboxylic acid and replacing the “–oic acid” with “–amide”.

Secondary and tertiary amide contains two parts in its name.  The alkyl groups that are bonded to the nitrogen atom is named using N- as the prefix for the alkyl group and this precedes the name.  The $\text{RCO}-$ group is named by the use of –amide as suffix.

Acceptable name has to be given for the below compound.

${\text{HCONHCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$
