Amines and Amides
2Nitrogen-Containing Functional Groups
• Nitrogen is in Group V of the periodic table, and in most of its compounds, it has three single bonds and one lone pair:
• In this chapter, we will take a look at two functional groups which contain nitrogen atoms connected to carbons: the amines and the amides.

3Classification and
Nomenclature of Amines
4Amines
• Amines and amides are abundant in nature. They are a major component of proteins and enzymes, nucleic acids, alkaloid drugs, etc. (Alkaloids are N-containing, weakly basic organic compounds; thousands of these substances are known.)
•Aminesare organic derivatives of ammonia, NH 3 , in which one or more of the three H's is replaced by a carbon group.• Amines are classified as primary(1°), secondary (2°), or tertiary(3°), depending on how many carbon groups are connected to the nitrogen atom.

5Examples: Classifying Amines
• Classify the following amines as primary (1°), secondary (2°), or tertiary (3°). NCH 3 CH 2 CH 2 H H NCH 3 CH 3 CH 3 CH 3 CH 2 CHCH 3 NH 2 NCH 3 CH 2 H CH 3NH N 6Nomenclature of Amines
•Simple 1°, 2°, and 3° amines: common (trivial) names are obtained by alphabetically arranging the names of the alkyl substituents on the nitrogen and adding the suffix -amine(e.g., ethylmethylamine).
•Amines in the IUPAC system: the "e" ending of the alkane name for the longest chain is replaced with -amine. The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using "N" as the position number. More complex primary amines are named with - NH
2 as the aminosubstituent.•Aromatic amines: named as derivatives of the parent compound aniline. Substituents attached to the nitrogen are indicated by using "N-" as the location number.
