The core −C(=O)−(N) of amides is called the amide group (specifically, carboxamide group). In the usual nomenclature, one adds the term "amide" to the stem of the parent acid's name. For instance, the amide derived from acetic acid is named acetamide (CH 3 CONH 2). IUPAC recommends ethanamide, but this and related formal names are rarely ...
Structures of three kinds of amides: an organic amide (carboxamide), a sulfonamide, and a phosphoramide. In chemistry, the term amide (/ ˈ æ m aɪ d / or / ˈ æ m ɪ d / or / ˈ eɪ m aɪ d /) [1] [2] [3] is a compound with the functional group R n E(=O) x NR 2, where x is not zero, E is some element, and each R represents an organic group or hydrogen.

Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −. Amido complexes of the parent amido ligand NH 2 − are rare compared to complexes with diorganylamido ligand, such as dimethylamido. Amide ligands have two electron pairs available for bonding.

2[((CH 3) 3 Si) 2 N] 2 S + 2SCl 2 + 2SO 2 Cl 2 → S 4 N 4 + 8 (CH 3) 3 SiCl + 2SO 2 Tetraselenium tetranitride , Se 4 N 4 , is a compound analogous to tetrasulfur tetranitride and can be synthesized by the reaction of selenium tetrachloride with [((CH
Specifically, an amide results from an acid, in which a carbon atom is double bonded to oxygen and also to a hydroxyl group, when the hydroxyl group is replaced by an amine. Subcategories This category has the following 13 subcategories, out of 13 total.
The molecules are linked by intermolecular hydrogen bonds, which allows the benzoyl ketone to rotate out of the plane of the amide. [1] For the general case of substituted acetoanilides, substituents on the aryl ring affect the balance of intra- vs intermolecular hydrogen bonding. [ 2 ]
An amide ring is employed in the specificity of the adaptor protein GRB2 for a particular asparagine within proteins it binds. GRB2 binds strongly to the pentapeptide EYINQ (when the tyrosine is phosphorylated); in such structures a 9-atom amide ring occurs between the amide side chain of the pentapeptide's asparagine and the main chain atoms ...
