Removal of cyanide from cassava in Nigeria. Cyanides are produced by certain bacteria, fungi, and algae.It is an antifeedant in a number of plants. Cyanides are found in substantial amounts in certain seeds and fruit stones, e.g., those of bitter almonds, apricots, apples, and peaches. [5]
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.
The name is derived from the separate words "laevorotatory" and "mandelonitrile". Laevorotatory describes the stereochemistry of the molecule, while mandelonitrile refers to the portion of the molecule from which cyanide is released by decomposition. [15] A 500 mg laetrile tablet may contain between 2.5 and 25 mg of hydrogen cyanide. [16]
Aldol condensation can occur when acetyl cyanide reacts with (Z)-but-2-enal to form (2E,4E)-hexa-2,4-dienoyl cyanide: The photochemical and thermal reactions of acetyl cyanide have been extensively studied. For example, formyl cyanide does not undergo unimolecular decomposition to HCN and CO spontaneously. However, acetyl cyanide, also a member ...

Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N. It is an azide compound of carbon and nitrogen. It is an oily, colourless liquid at room temperature. [2] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.
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]
