The amino group (NH 2) is named as a substituent in more complicated amines, such as those that incorporate other functional groups or in which the alkyl groups cannot be simply named. Example \(\PageIndex{1}\)
In chemistry, the amino radical, ·NH2, also known as the aminyl radical or azanyl radical, is the neutral form of the amide ion ( NH− 2 ). Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry.
This system names amine functions as substituents on the largest alkyl group. The simple -NH substituent found in 1º-amines is called an amino group. For 2º and 3º-amines a compound prefix (e.g. dimethylamino in the fourth example) includes the names of all but the root alkyl group.
The substituent −NH2 is called an amino group. [6] Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure R−C (=O)−NR′R″, are called amides and have different chemical properties from amines. Classification of amines. Amines can be classified according to the nature and number of substituents on nitrogen.
Amines are the derivatives of ammonia (remember NH 3 from General chemistry). Replacing one hydrogen of ammonia with an alkyl group forms an amine with a general formula of R-NH 2: Depending on the number of alkyl groups are connected to the nitrogen, we have primary, secondary, and tertiary amines:

Solution. 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.
May 26, 2024 · amino acid, any of a group of organic molecules that consist of a basic amino group (―NH 2 ), an acidic carboxyl group (―COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid.
Primary amines are named in the IUPAC system in several ways. For simple amines, the suffix - amine is added to the name of the alkyl substituent. You might also recall from the chapter on Benzene and Aromaticity that the aromatic phenylamine, H 2 N–C 6 H 5 , has the common name aniline.
When naming the ester, the name of the R in the OR group is stated first, followed by the name of the acid, with “oic acid” replaced by “oate”. As a net result, the R in the OR is regarded as the “substituent”, even though it is not.
