Benzonitrile is a chemical compound with the molecular formula C7H5N. The spelling of the word "benzonitrile" can be explained using the International Phonetic Alphabet (IPA) notation. The first syllable is "benz", pronounced as /bɛnz/, with a short "e" sound as in "bed". The second syllable is "o", pronounced as /əʊ/, with a long "o" sound as in "go". The final syllable is "nitrile", pronounced as /ˈnaɪtraɪl/, with the stress on the first syllable and the "i" pronounced as a long "i" sound as in "bite".
Benzonitrile is an organic compound with the chemical formula C6H5CN. It is a colorless liquid that has a distinct almond-like odor. Benzonitrile is classified as a nitrile, which means it contains a carbon atom triple-bonded to a nitrogen atom. It is also referred to as phenyl cyanide due to its chemical structure, which consists of a phenyl group attached to a cyano (CN) group.
Benzonitrile is mainly used as a solvent in various industrial applications, including pharmaceuticals, dyes, and polymers. It has a low boiling point and is relatively volatile, making it ideal for use in liquid-phase reactions and extraction processes. Additionally, benzonitrile can be used as a precursor for the synthesis of other chemicals, such as benzylamines and benzylsulfonamides.
In terms of its chemical reactivity, benzonitrile is relatively stable and does not easily undergo chemical transformations. However, its cyano group can participate in a range of reactions, including nucleophilic substitution, reduction, and hydrolysis. These reactions allow for the synthesis of various derivatives and substituted compounds.
From a safety perspective, benzonitrile is considered toxic and should be handled with caution. It can irritate the skin, eyes, and respiratory system upon contact or inhalation. Proper handling procedures, including the use of appropriate protective equipment, should be followed when working with this compound.

The word "benzonitrile" comes from a combination of two words: "benzo" and "nitrile".
- The term "benzo" is derived from "benzene", which refers to a six-carbon aromatic ring structure. "Benzene" ultimately originates from the German word "Benzin", meaning "gasoline", which was derived from "benzoin", a resin that was used to produce a similar-smelling substance.
- The suffix "-nitrile" is added to the name "benzo" to indicate the presence of a nitrile functional group (-CN) within the molecule of benzonitrile. The term "nitrile" comes from the French word "nitryle", which is a derivative of the Latin word "nitrum", meaning "saltpeter", as nitriles were initially derived from this compound.
