Unit 6- Amines & Amides

What is an amine?

nitrogen in between a combination of hydrogen atoms and hydrocarbon-type carbons

• nitrogen=amino group

• weakly basic because of very active lone electron pair on N

Classification of amines & amides 

(tertiary amines cannot hydrogen bond therefor lower bp)

IUPAC Nomenclature for amines

1. find longest continuous carbon chain containing amino group (N)

2. remove “-e” from corresponding alkane name and replace it with “-amine”

3. number parent chain giving amino group lowest numerical designation 

4. name secondary and tertiary with “N-alkyl” prefix 

Acid-Base reaction of amines 

What is an amide?

Nitrogen between carbonyl carbon (C==O) and combination of hydrogens or hydrocarbon-type carbons

• fusion between carboxylic acid and amine functional group

• not basic like amines

IUPAC nomenclature for amides 

1. find longest continuous chain of carbons containing amide carbonyl 

2. remove “-e” from corresponding alkane name replacing it with “-amide”

3. no need to number parent chain because 1 designation always on carbonyl carbon 

4. name secondary and tertiary amides with “N-alkyl” prefix
