cyano radical

A chemist draws the cyano radical on a whiteboard.

Definition
  1. Noun:
    • The monovalent group -CN in a chemical compound: The "cyano radical" refers to the functional group consisting of a carbon atom triple-bonded to a nitrogen atom, with the formula -C≡N or -CN. It is a radical (meaning it has an unpaired electron) and is a key structural unit in many chemical compounds.
Usage Examples
  • Noun:
    • The presence of a cyano radical in the molecule increases its acidity.
    • This polymer is synthesized using a monomer containing a cyano radical.
Advanced Usage
  • In chemical nomenclature: The term is used to specify the -CN group when discussing reaction mechanisms or molecular structure, particularly in organic chemistry contexts.
    • The reaction proceeds via the abstraction of a hydrogen atom by the cyano radical.
Variants and Related Words
  • Cyano group (n): Often used interchangeably, though "cyano group" is more common in general contexts, while "cyano radical" specifically denotes its radical nature.
  • Cyanide ion (n): The negatively charged anion CN⁻, which is distinct from the neutral radical.
  • Nitrile (n): An organic compound containing the -C≡N group bonded to an alkyl or aryl group (e.g., acetonitrile, CH₃CN).
Synonyms
  • CN group: A direct abbreviation.
  • Cyanide radical: A less common but technically accurate synonym.
Related Phrases
  • Cyano-functionalized: Describing a material or molecule to which a cyano group has been attached.
    • The cyano-functionalized surface showed improved adhesion.
