Cyanodiacetylene
In organic chemistry, cyanopolyynes are a family of organic compounds with the chemical formula (''n'' = 3,5,7,…) and the structural formula (''n'' = 1,2,3,…). Structurally, they are polyynes with a cyano group () covalently bonded to one of the terminal acetylene units (). A rarely seen group of molecules both due to the difficulty in production and the unstable nature of the paired groups, the cyanopolyynes have been observed as a major organic component in interstellar clouds. This is believed to be due to the hydrogen scarcity of some of these clouds. Interference with hydrogen is one of the reason for the molecule's instability due to the energetically favorable dissociation back into hydrogen cyanide and acetylene. Cyanopolyynes were first discovered in interstellar molecular clouds in 1971 using millimeter wave and microwave telescopes. Since then many higher weight cyanopolyynes such as and have been discovered, although some of these identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanoacetylene
Cyanoacetylene is an organic compound with formula or . It is the simplest cyanopolyyne. Cyanoacetylene has been detected by spectroscopic methods in interstellar clouds, in the coma of comet Hale–Bopp and in the atmosphere of Saturn's moon Titan, where it sometimes forms expansive fog-like clouds. Cyanoacetylene is one of the molecules that was produced in the Miller–Urey experiment. : H-C#C-H + H-C#N -> H-C#C-C#N + H2 See also * Dicyanoacetylene, N≡C−C≡C−C≡N *Diacetylene, H−C≡C−C≡C−H * Cyanogen, N≡C−C≡N * Hydrocyanic acid, H−C≡N *Polyyne In organic chemistry, a polyyne () is any organic compound with alternating single and triple bonds; that is, a series of consecutive alkynes, with ''n'' greater than 1.
