Hydrogen isocyanide (HNC) is a linear triatomic molecule with C ∞v point group symmetry.It is a zwitterion and an isomer of hydrogen cyanide (HCN). [2] Both HNC and HCN have large, similar dipole moments, with μ HNC = 3.05 Debye and μ HCN = 2.98 Debye respectively. [3]
Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen.The tautomer of HCN is HNC, hydrogen isocyanide. [citation needed]HCN has a faint bitter almond-like odor that some people are unable to detect owing to a recessive genetic trait. [12]
Low-temperature photolysis of solids containing HNCO creates the tautomer cyanic acid H−O−C≡N, also called hydrogen cyanate. [15] Pure cyanic acid has not been isolated, and isocyanic acid is the predominant form in all solvents. [2] Sometimes information presented for cyanic acid in reference books is actually for isocyanic acid ...
The following tables list molecules that have been detected in the interstellar medium or circumstellar matter, grouped by the number of component atoms.Neutral molecules and their molecular ions are listed in separate columns; if there is no entry in the molecule column, only the ionized form has been detected.
HNC may refer to: Hydrogen isocyanide, a molecule with the formula HNC that is important to the field of astrochemistry; Heptanitrocubane, an experimental high explosive; Higher National Certificate, a higher education qualification in the United Kingdom; High Negotiations Committee, a Syrian political-military opposition bloc headquartered in ...
Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric. 4 He 3, the helium trimer is only weakly bound by van der Waals force and is in an Efimov state. [1] Trisulfur (S 3) is analogous to ozone.
Fulminic acid was long believed to have a structure of H–O–N + ≡C −.It wasn't until the 1966 isolation and analysis of a pure sample of fulminic acid that this structural idea was conclusively disproven. [3]
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
