The chemical cyanide has the chemical formula CN−
Inhibits the body's use of oxygen and works quickly. Colorless compound hydrogen cyanide HCN
and cyanogen chloride CNCl
is an example of cyanide. Certain bacteria, fungi, and algae can produce cyanide. In metallurgy, cyanide salts are used in electroplating, metal cleaning, and extraction of gold from ores. In ships and buildings, cyanide gas is used to kill vermin and rodents.

Cyanide Formula

The compound cyanide consists of a cyano group, which is formed when a carbon atom is triple bonded to a nitrogen atom. The chemical or molecular formula for cyanide is CN−

The structure of cyanide

Anything with a monovalent linking group CN is considered a cyanide. This group is present in inorganic cyanides such as sodium cyanide (NaCN), which is known as hydrocyanate. These substances are extremely dangerous.

The structure of cyanide is shown in the following diagram:
Cyanide is a chemical molecule with C=N
functional group

The triple bond between the carbon atom and the nitrogen atom forms the group, called a cyano group. The cyanide group exists in inorganic cyanide in the form of cyanide anion, symbol -C=N

Carbon has an extra valence electron to complete its octet and shares three valence electrons with nitrogen. The extra valence electrons accepted by the carbon atom enable it to acquire a negative charge.

Due to the triple bond between nitrogen and carbon, two additional pi bonds are necessary. Since only one of nitrogen's p orbitals is available for hybridization,

Since the chemical bond between nitrogen and carbon is a triple bond, two pi bonds are also required in this case. This suggests that only one nitrogen p orbital is available for hybridization, resulting in a "sp" of nitrogen hybridization in HCN.
