The exact IUPAC name of acetamide is Ethanamide.
Understanding Acetamide and its Nomenclature
Acetamide is a simple organic compound with the chemical formula CH₃CONH₂. It is the simplest amide derived from acetic acid, where the hydroxyl group (-OH) of acetic acid is replaced by an amino group (-NH₂). This modification results in a crucial functional group known as the amide group (-CONH₂).
The IUPAC (International Union of Pure and Applied Chemistry) naming system provides a standardized method for naming chemical compounds, ensuring clarity and consistency worldwide. For amides, the general rule involves taking the name of the corresponding carboxylic acid, replacing the '-oic acid' or '-ic acid' suffix with '-amide', and dropping the 'e' from the alkane name if applicable.
Breaking Down "Ethanamide"
The name "Ethanamide" systematically describes the structure of acetamide:
- "Ethan-": This prefix indicates a two-carbon chain. In organic chemistry, 'eth-' signifies two carbon atoms. Acetamide is derived from acetic acid, which also has a two-carbon backbone (CH₃COOH).
- "-amide": This suffix denotes the presence of the amide functional group (-CONH₂). This group is characteristic of compounds formed by the condensation reaction between a carboxylic acid and ammonia or an amine.
This systematic naming ensures that its structure, a two-carbon chain containing an amide functional group, is immediately understood by chemists globally. For more detailed information on amide nomenclature, you can refer to resources on organic chemistry functional groups.
Other Identifiers for Acetamide
While Ethanamide is the definitive IUPAC name, acetamide is also recognized by other common names and identifiers, which are useful for various applications, including research and industrial processes.

The Amide Functional Group
Amides are an important class of organic compounds found in many natural and synthetic substances, including proteins, nylon, and pharmaceuticals. The amide linkage is particularly stable due to the resonance between the carbonyl group and the nitrogen atom, which imparts partial double-bond character to the C-N bond. This stability is crucial for their biological and industrial significance. For instance, peptide bonds, which link amino acids together to form proteins, are a specific type of amide bond.
