Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH 2. It is a salt composed of the sodium cation and the azanide anion. This solid, which is dangerously reactive toward water, is white, but commercial samples are typically gray due to the presence of small quantities of ...
In the first step, ammonia is converted to sodium amide by metallic sodium: 2 Na + 2 NH 3 → 2 NaNH 2 + H 2. It is a redox reaction in which metallic sodium gives an electron to a proton of ammonia which is reduced in hydrogen gas. Sodium easily dissolves in liquid ammonia to produce solvated electrons responsible for the blue color of the ...
Sodium amide (also known as sodamide) is synthesized from sodium metal and ammonia with ferric nitrate catalyst. [3] [4] The sodium compound is white, but the presence of metallic iron turns the commercial material gray. 2 Na + 2 NH 3 → 2 NaNH 2 + H 2. Lithium diisopropylamide is a popular non-nucleophilic base used in organic synthesis.
As hydrazoic acid, the protonated form of the azide anion, has a very low reduction potential E° red = -3,09 volt, and is even a stronger reductant than lithium (E° red = -3.04 volt), dry solid sodium azide can be added to molten metallic sodium (E° red = -2,71 volt) under strict anoxic conditions (e.g., in a special anaerobic glovebox with ...
As an example, consider the gas-phase reaction NO 2 + CO → NO + CO 2.If this reaction occurred in a single step, its reaction rate (r) would be proportional to the rate of collisions between NO 2 and CO molecules: r = k[NO 2][CO], where k is the reaction rate constant, and square brackets indicate a molar concentration.
It is a sodium salt of acetylene, consisting of sodium cations Na + and hydrogen acetylide anions − C≡CH. It is a derived from acetylene by deprotonation using a sodium base, typically sodium amide. [2] HC≡CH + NaNH 2 → NaC≡CH + NH 3
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 ...
A lithium–ammonia solution at −60 °C is saturated at about 15 mol% metal (MPM). When the concentration is increased in this range electrical conductivity increases from 10 −2 to 10 4 Ω −1 cm −1 (larger than liquid mercury). At around 8 MPM, a "transition to the metallic state" (TMS) takes place (also called a "metal-to-nonmetal ...
