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 (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N. It is a highly toxic and flammable liquid that boils slightly above room temperature , at 25.6 °C (78.1 °F).
Isocyanic acid is a chemical compound with the structural formula HNCO, which is often written as H−N=C=O. It is a colourless, volatile and poisonous gas, condensing at 23.5 °C. It is the predominant tautomer and an isomer of cyanic acid (aka. cyanol) ( H−O−C≡N ), and the monomer of cyanuric acid .
Cyanogen is the chemical compound with the formula (C N) 2. The simplest stable carbon nitride, it is a colorless and highly toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups ‒ analogous to diatomic halogen molecules, such as Cl 2, but far less oxidizing.
It is a colorless salt, similar in appearance to sugar, that is highly soluble in water. Most KCN is used in gold mining, organic synthesis, and electroplating. Smaller applications include jewellery for chemical gilding and buffing. [4] Potassium cyanide is highly toxic, and a dose of 200 to 300 milligrams will kill nearly any human.
The most hazardous compound is hydrogen cyanide, which is a gas and kills by inhalation. For this reason, working with hydrogen cyanide requires wearing an air respirator supplied by an external oxygen source. [11] Hydrogen cyanide is produced by adding acid to a solution containing a cyanide salt.
The C-N distance in isocyanides is 115.8 pm in methyl isocyanide.The C-N-C angles are near 180°. [3]Akin to carbon monoxide, isocyanides are described by two resonance structures, one with a triple bond between the nitrogen and the carbon and one with a double bond between.
