Imide is a chemical term used to describe a class of organic compounds containing the imide functional group (-C(=O)NH-) and is pronounced [ɪmˈaɪd]. The first syllable is pronounced with the short "i" sound as in "imagine," followed by the syllable "mide" which is pronounced with a long "i" sound as in "tide." The spelling of this word follows English phonetic and pronunciation rules, with the "-ide" suffix indicating a functional group and the letter "i" representing the vowel sound in the word.
An imide is a type of organic compound that consists of two carbonyl groups, each attached to a nitrogen atom. It is classified as a functional group and is derived from the combination of a carboxylic acid and ammonia or an amine. The general formula of an imide is R-CO-NR'-CO-R", where R, R', and R" represent various groups or atoms.
Imides typically exhibit a high degree of stability due to the resonance stabilization of the carbonyl groups. They can exist as both cyclic and acyclic structures, depending on the arrangement of the nitrogen atoms. Imides are commonly found in pharmaceuticals, dyes, polymers, and other industrial chemicals, where they contribute to the desired properties of these compounds.
Due to their diverse applications, imides have a wide range of chemical and physical properties. They can be highly reactive towards nucleophiles or electrophiles, allowing them to participate in various chemical reactions such as hydrolysis, reduction, and substitution. Imides can also exhibit good thermal stability, making them suitable for high-temperature processes.
In summary, an imide is an organic compound that contains two carbonyl groups attached to nitrogen atoms. It is known for its stability and versatility, making it an important functional group in various industries.
A chemical compound derived from a dicarboxylic, acid by the substitution of NH for 2OH, or one in which two hydrogen atoms of the ammonia molecule are replaced by a divalent acid radicle.

The word "imide" originates from the combination of two Greek terms: "imis" meaning "common" or "equal" and "eidos" meaning "appearance" or "shape". This combination emphasizes the similarity of imides to other chemical compounds in terms of their appearance and structure. In fact, imides are characterized by the presence of the functional group -C(O)NH-, which is similar to amides (-C(O)NH2) but with the replacement of a hydrogen atom by a different substituent or atom.
