Cyanocarbon

Cyanocarbons are a group of chemical compounds that contain several cyanide functional groups. Such substances generally are classified as organic compounds, since they are formally derived from hydrocarbons by replacing one or more hydrogen atoms with a cyanide group.[1] The parent member is C(CN)4 (tetracyanomethane, also known as carbon tetracyanide). Organic chemists often refer to cyanides as nitriles.

In general, cyanide is an electronegative substituent. Thus, for example, cyanide-substituted carboxylic acids tend to be stronger than the parents. The cyanide group can also stabilize anions by delocalizing negative charge as revealed by resonance structures.

Definition and examples

Cyanocarbons are organic compounds bearing enough cyano functional groups to significantly alter their chemical properties.[1]

Important cyanocarbons:

gollark: Browser diversity is important. We can't let Google monopolise the webs.
gollark: Use Firefox.
gollark: How expensive is DDR4-3000 right now? I need another 8GB.
gollark: I actually do that really often when working on potatOS.
gollark: `setData` is different and edits the 256-byte data section.
