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 ).
The carbide powder is heated at about 1000 °C in an electric furnace into which nitrogen is passed for several hours. [12] The product is cooled to ambient temperatures and any unreacted carbide is leached out cautiously with water. CaC 2 + N 2 → CaCN 2 + C (ΔH o f = –69.0 kcal/mol at 25 °C)
Cyanamide is the name for a functional group with the formula R 1 R 2 N−C≡N where R 1 and R 2 can be a variety of groups. These compounds are called cyanamides . One example is naphthylcyanamide, C 10 H 7 N(CH 3 )CN, which has been produced by the von Braun reaction , [ 19 ] a general method for the conversion of tertiary amines to ...
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.

[2] A CN bond is strongly polarized towards nitrogen (the electronegativities of C and N are 2.55 and 3.04, respectively) and subsequently molecular dipole moments can be high: cyanamide 4.27 D, diazomethane 1.5 D, methyl azide 2.17, pyridine 2.19. For this reason many compounds containing CN bonds are water-soluble.
For organic compounds, the length of the C-O bond does not vary widely from 120 picometers. Inorganic carbonyls have shorter C-O distances: CO, 113; CO 2, 116; and COCl 2, 116 pm. [2] The carbonyl carbon is typically electrophilic. A qualitative order of electrophilicity is RCHO (aldehydes) > R 2 CO (ketones) > RCO 2 R' (esters) > RCONH 2 (amides).
Amides are the members of a group of organic chemical compounds containing nitrogen. 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 .
MCl n + n LiNR 2 → M(NR 2) n + n LiCl MCl n + 2n HNR 2 → M(NR 2) n + n HNR 2 ·HCl. Transition metal amide complexes have been prepared by these methods: [6] treating a halide complex with an alkali amide; deprotonation of a coordinated amine; oxidative addition of an amine; Structure of the nitride-amido complex NMo(N(t-Bu)(C 6 H 3 Me 2) 3 ...
