What is the name of CN?

Published in Chemistry 1 min read

The name of CN is the cyano group or cyanide ion.

Explanation

CN represents a chemical species consisting of a carbon atom triple-bonded to a nitrogen atom. Depending on its form, it can be referred to as either the cyano group or the cyanide ion.

  • Cyano Group: When CN is covalently bonded to another atom or molecule (e.g., in acetonitrile, CH3CN), it is called a cyano group. It acts as a functional group within the larger molecule.

  • Cyanide Ion: When CN carries a negative charge (CN-), it exists as an ion and is referred to as the cyanide ion. Cyanide ions are highly toxic.

Key Characteristics

  • Chemical Formula: CN (cyano group), CN- (cyanide ion)
  • Bonding: Carbon and nitrogen are connected by a triple bond.
  • Toxicity: Cyanide ions are extremely poisonous, interfering with cellular respiration.
  • Occurrence: Found in various chemical compounds, including nitriles and cyanide salts.

Summary

CN, as a chemical entity, can be either a cyano group when covalently bound within a molecule, or a cyanide ion when existing as an anion with a negative charge. Both forms share the core carbon-nitrogen triple bond but have different implications for chemical reactivity and toxicity.
