Secondary (2°) amines —Secondary amines have two organic substituents (alkyl, aryl or both) bound to the nitrogen together with one hydrogen. Important representatives include dimethylamine, while an example of an aromatic amine would be diphenylamine. Tertiary (3°) amines —In tertiary amines, nitrogen has three organic substituents.

胺 àn （英語： amine）或 胺类[1]，是 氨 分子中的一个或多个 氢 原子被 烃基 取代 后形成的一类 有机化合物 [2][3]。 胺基 [註 1] （－NH 2 、－NHR、－NR 2）是胺的 官能团。 如果氮原子连着 羰基 （C=O），那么该化合物则称为 醯胺，其化学性质与胺并不相同。 在中国大陆（即便繁体），“胺”（读作：àn/ㄢˋ）字仅用作 化学名 後綴，即当氨基（－NR 2）是化合物“主要官能团”时，称为某某胺，如： 亚硝胺 等；当氨基（－NR 2）作为“次要官能团”时，则此官能团名称改 …

Amines are classified as primary, secondary, or tertiary based on the number or organic substituents directly attached to the nitrogen. An amine attached to one substituent is primary (1 o), two substituents is secondary (2 o), and three substituents is tertiary (3 o).

2020年1月28日 · They increase electron density on nitrogen atom; therefore, amines can donate electron pair more easy than ammonia. On the basis above conclusion the expected order of basic nature of amines is 3°amine > 2°amine > 1° amine …

Amines are derived from ammonia (NH 3), in which alkyl or aryl groups replace one or more hydrogen atoms. 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.

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: …
