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.
