Cyanide

In organic chemistry compounds containing a -C≡N group are known as nitriles and compounds that contain the -N≡C group are known as isocyanides. Organic nitriles and isocyanides are far less toxic because they do not release cyanide ions easily. The dye Prussian blue had been first accidentally made, it is presumed around 1706, from substances containing iron and carbon and nitrogen, and the (then unknown) cyanide was formed during the manufacture of the dye. An iron -containing compound was found in Prussian blue and named " ferrocyanide ", meaning "blue substance with iron", from Latin // ferrum // = "iron" and Greek // kyanos // = "(dark) blue". When ferrocyanide was analyzed, removing the iron from the compound and from its name left "cyanide".
 * Cyanide** is a chemical compound that contains the **cyano group**, -C≡N, which consists of a carbon atom triple-bonded to a nitrogen atom.Cyanides most commonly refer to salts of the anion CN−, which is isoelectronic with carbon monoxide and with molecular nitrogen. Most cyanides are highly toxic.

Cyanides are generally highly toxic that are rapidly acting and exist in various forms. It can be a colorless gas, such as hydrogen cyanide, or a crystal form such as sodium cyanide. It's been known to have a bitter almond smell, but doesn't always give off odor. It is a chemical compound that contains a cyano group, which is a carbon atom triple-bonded to a nitrogen atom. Cyanides are commonly in their anionic form (CN-), which are present in many salts.

Cyanides are produced by many bacteria, fungi, algae, and a number of plants. The cyanide anion is a n inhibitor of the enzyme cytochrome c oxidase. When the cyanide binds, it disrupts the flow of electrons to oxygen. This causes disruptions in the central nervous system and the heart.

The kidneys eliminate cyanocobalamin when a reaction between cyanide and hydroxocobalamin occurs. The formation of methemoglobin is being avoided by this type of method. The antidote is called Cyanokit and approved in 2006 by the FDA.

Nazi soldiers in in World War II kept cyanide pills on them just in case they we're captured. They would bite down on the capsle, killing them with in minutes.
