Cyano vs. Nitrile — What's the Difference?
By Maham Liaqat & Urooj Arif — Updated on April 18, 2024
Cyano refers specifically to the functional group -C≡N in organic chemistry, integral to nitrile compounds; nitrile is the term for organic compounds containing the cyano group, usually attached to an alkyl or aryl group.

Key Differences
The term "cyano" specifically describes the cyano functional group (-C≡N), which is a carbon atom triple-bonded to a nitrogen atom. This group is a key feature in the chemistry of compounds containing this linkage. On the other hand, "nitrile" refers to any organic compound that incorporates the cyano group, typically attached to carbon-containing groups such as alkyl or aryl radicals.
While "cyano" is used to denote the presence of the -C≡N group within a larger molecule and is often used as a prefix in chemical nomenclature (e.g., cyanoacrylates, cyanobenzene), "nitrile" is used to classify a broader category of organic compounds. Nitriles are characterized by this functional group but are identified more generally by their structural context and properties.
The cyano group is known for its electronegativity due to the nitrogen atom, influencing the chemical behavior of the molecule, such as increasing acidity and reactivity. In contrast, nitriles as a class of compounds are recognized for their application in various industrial and pharmaceutical contexts, including the production of plastics, drugs, and synthetic fibers.
From a synthetic perspective, the cyano group in nitriles can be utilized in various chemical reactions, serving as a functional handle for further transformations. Nitrile compounds themselves are often synthesized from alcohols or halides through cyanation reactions.
In practical applications, you might encounter the term "cyano" when discussing specific functional groups within a molecule during chemical analysis or synthesis. "Nitrile," however, is more likely to appear in the context of material science, such as in the naming of nitrile rubber, or in discussions related to organic synthesis and pharmaceuticals.
