    Amines are classified as primary, secondary, or tertiary depending on whether one, two, or three of the hydrogen atoms of ammonia have been replaced by organic groups. In chemical notation these three classes are represented as RNH 2, R 2 NH, and R 3 N, respectively.

    How are amines classified?
    Amines are classified according to the number of carbon atoms bonded directly to the nitrogen atom. A primary (1°) amine has one alkyl (or aryl) group on the nitrogen atom, a secondary (2°) amine has two, and a tertiary (3°) amine has three (Figure 3.1.1 3.1. 1).

    What is the structure of an amine?
    They are characterized by the presence of a nitrogen atom bonded to carbon atoms and hydrogen atoms. The general formula of an amine is RNH 2, where R represents the alkyl or aryl group. The structure of amines revolves around the central nitrogen atom bonded to various substituents.

    Is amine a tertiary amine?
    There is only one alkyl group attached to the nitrogen atom, so the amine is primary. A group of three carbon atoms (a propyl group) is attached to the NH 2 group through an end carbon atom, so the name is propylamine. There are two methyl groups and one ethyl group on the nitrogen atom. The compound is ethyldimethylamine, a tertiary amine.

    Which amine is classified as 1o amine?
    The first two are classified as 1º-amines, since only one alkyl group is bonded to the nitrogen; however, the alkyl group is primary in the first example and tertiary in the second. The third and fourth compounds in the row are 2º and 3º-amines respectively. The bottom row shows the structures for some common amines that need to be memorized.

    Which amine is a primary alkyl amine?
    Important primary alkyl amines include methylamine, most amino acids, and the buffering agent tris, while primary aromatic amines include aniline. Secondary (2°) amines —Secondary amines have two organic substituents (alkyl, aryl or both) bound to the nitrogen together with one hydrogen.

    What is a primary amine?
    Primary (1°) amines —Primary amines arise when one of three hydrogen atoms in ammonia is replaced by an alkyl or aromatic group. Important primary alkyl amines include methylamine, most amino acids, and the buffering agent tris, while primary aromatic amines include aniline.
