amide chemistry definition
Ammonia. Amines are organic compounds which contain and are often actually based on one or more atoms of nitrogen. Structurally amines resemble ammonia in that the nitrogen can bond up to three hydrogens, but amines also have additional properties based on their carbon connectivity. Amides are derived from a reaction between an amine and a carboxylic acid. Between these two molecules we have two competing nucleophiles, the oxygen of the alcohol group in the carboxylic acid molecule and the nitrogen of the amine. Organic-nitrogen compounds containing metals are also called amides, so if you see a molecule that has a nitrogen and either a carbonyl group or a metal next to that nitrogen, then you know that molecule should be an amide instead of an amine. amide | amides.

For primary amines, where the amine is not the principal characteristic group, the prefix amino- is used. For example: 4-aminobenzoic acid where the carboxylic acid is the principal characteristic. Otherwise, the suffix -amine is used with with either the parent hybride or the R group substituent name. Amines can be either primary, secondary or tertiary, depending on the number of carbon-containg groups that are attached to them. If there is only one carbon-containing group (such as in the molecule CH 3 NH 2) then that amine is considered primary. Amide. a compound with the functional group R n E(O) x NR' 2. Most common are organic amides, but many other important types of amides are known including phosphor amides and sulfonamides. By Anne Marie Helmenstine, Ph.D. Definition: An amine is a compound in which one or more of the hydrogen atoms in ammonia have been replaced by an organic functional group. Amines are generally weak bases. Further, most amines are organic bases. Amines have the prefix amino-or the suffix-amine included in their name. Examples: Methylamine is an amine. In simple amides, two hydrogen atoms are bonded to the nitrogen (-CONH2) while in more complex amides, the nitrogen is bonded to one or two aliphatic or aromatic groups (-CONR).
