23.1: Properties of amines - Chemistry LibreTexts
WEBIn an amine, one or more of the hydrogen atoms from ammonia are replaced by organic substituents like alkyl (alkane chain) and aryl (aromatic ring) groups. Another type of organic molecule contains nitrogen without being, strictly speaking, an amine : carboxylic acid derivatives containing a trivalent (three-bond) ammonia in ground state are ...
Amine - Wikipedia
WEBAromatic amines have the nitrogen atom connected to an aromatic ring. Amines, alkyl and aryl alike, are organized into three subcategories (see table) based on the number of carbon atoms adjacent to the nitrogen (how many hydrogen atoms of the ammonia molecule are replaced by hydrocarbon groups): [6][7]
24.10: Spectroscopy of Amines - Chemistry LibreTexts
WEBPrimary and secondary amines can be identified by a characteristic N–H stretching absorption in the 3300 to 3500 cm –1 range of the IR spectrum. Alcohols also absorb in this range (Section 17.11), but amine absorption bands are generally sharper and less intense than hydroxyl bands. Primary amines show a pair of bands at about 3350 and 3450 ...
24.1: Naming Amines - Chemistry LibreTexts
WEBWhen present in a compound with a functional group of higher priority, the amine group is named as a substituent called “amino.” Heterocyclic amine have one or more nitrogens as part of the ring and can be aliphatic or aromatic. Most heterocyclic amine ring systems have a common name and are numbered such that a nitrogen always gets position 1.

WEBIn an amine, one or more of the hydrogen atoms from ammonia are replaced by organic substituents like alkyl (alkane chain) and aryl (aromatic ring) groups.
Heterocyclic amine - Wikipedia
WEBHeterocyclic amines, also sometimes referred to as HCAs, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group.
24.9 Heterocyclic Amines - Organic Chemistry - OpenStax
WEBAs noted in Section 15.5 in connection with a discussion of aromaticity, a cyclic organic compound that contains atoms of two or more elements in its ring is a called a heterocycle. Heterocyclic amines are particularly common, and many have important biological properties.
Amines - Formula, Structure, Nomenclature, Classification, …
WEBAn amine is generally a functional group with a nitrogen atom having a lone pair. Amines resemble ammonia structurally where nitrogen can bond up to 3 hydrogen atoms. It is also characterized by various properties that are based on carbon connectivity.
15.11 Amines: Structures and Names - Lumen Learning
WEBThe primary amine in which the nitrogen atom is attached directly to a benzene ring has a special name—aniline. Aryl amines are named as derivatives of aniline.
Aromatic amine - Wikipedia
WEBIn organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH2. Such compounds occur widely. [1]
