HCN is formed in interstellar clouds through one of two major pathways: via a neutral-neutral reaction (CH 2 + N → HCN + H) and via dissociative recombination (HCNH + + e − → HCN + H). The dissociative recombination pathway is dominant by 30%; however, the HCNH + must be in its linear form. See more Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the formula HCN and structure H−C≡N. It is a colorless, extremely poisonous, and flammable liquid that boils slightly above room temperature, … See more Hydrogen cyanide will react with alkenes under catalysis of nickel complexes. This reaction is called hydrocyanation. RCH=CH2 + HCN → RCH2-CH2-CN Four molecules of HCN will tetramerize into diaminomaleonitrile, which can be converted to … See more Hydrogen cyanide forms in at least limited amounts from many combinations of hydrogen, carbon, and ammonia. Hydrogen cyanide is currently produced in great quantities by several processes, as well as being a recovered waste product from the … See more HCN is obtainable from fruits that have a pit, such as cherries, apricots, apples, and bitter almonds, from which almond oil and flavoring are made. Many of these pits contain small … See more Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide.
