DEFINITION: Amines are organic derivatives of ammonia, in which one, two, or all three of the hydrogens of ammonia are replaced by organic groups. General formula: ROH. General formula: R-NH-R’ where R and R’ may be same or different alkyl group. In chemical notation these three classes are represented as RNH2, R2NH, and R3N, respectively. Amine molecules have the general formula of R3-xNHx where R is a hydrocarbon group and 0 < x < 3. An amine is a derivative of ammonia (NH3) in which one or more of the hydrogen atoms are replaced with a substituent groups such as an alkyl or aryl groups. The general reaction of nitrous acid with secondary amines is given below: ${{R}_{2}}-NH\xrightarrow{HN{{O}_{2}}}{{R}_{2}}-N-NO$ Note: When the primary amine is treated with nitrous acid then the formed alcohol will be also primary. Secondary (2 o) Amine : alkyl groups replace 2 hydrogen atoms in the ammonia molecule The amine functional group (NH) occurs between 2 carbon atoms. Below is an example of one when the amine used was secondary (2˚) and cyclic. Secondary and tertiary amides are named differently to show the two (or three) carbon chains. A primary (1°) amine A compound that has only one alkyl or aryl group on the nitrogen atom. It is like an ammonia molecule (NH 3) in which two of the hydrogens have been replaced by alkyl groups. The number of primary, secondary and tertiary amines possible with molecular formula C 3. . Secondary amines are converted to hydroxylamines, R 2 NOH, and tertiary amines to amine oxides, R 3 NO. General formula: algebraic formula for a homologous series e.g. Most primary amines are good ligands for metal ions to give coordination complexes. B. Since nitrogen has a normal valence of three, we can also conclude that there are two N-H bonds in primary amines and one N-H bond in secondary amines.
