Provide the correct common name for the compound shown here. ‘N r N,N-diethyl eth an amine
The correct answer and explanation is:
The correct common name for the compound “N,N-diethyl ethan amine” is N,N-Diethylamine.
Explanation:
This compound belongs to a class of organic compounds called amines, which are derivatives of ammonia (NH₃) in which one or more hydrogen atoms are replaced by alkyl groups. In the case of N,N-Diethylamine, the structure consists of an amine group (-NH₂) where both hydrogen atoms are replaced by ethyl groups (-C₂H₅). Here’s a breakdown of its name:
- Ethanamine: The base name “ethanamine” refers to the compound with the formula C₂H₅NH₂, which is the simplest amine derived from ethanol (C₂H₅OH). This compound consists of an amine group (-NH₂) attached to an ethyl group (-C₂H₅), making it an amine of ethane.
- N,N-Diethyl: The “N,N” part of the name indicates that both of the substituents attached to the nitrogen atom are ethyl groups. In other words, the nitrogen atom is bonded to two ethyl groups (C₂H₅). The “diethyl” part of the name signifies that both substituents are ethyl groups.
Nomenclature:
The systematic name follows the International Union of Pure and Applied Chemistry (IUPAC) rules. The structure consists of an ethyl group attached to a nitrogen atom, and a second ethyl group also attached to the nitrogen, making it a secondary amine (because two organic groups are attached to the nitrogen atom).
In summary, the common name of N,N-Diethylamine is straightforward because of its structure and the use of standard IUPAC nomenclature. It’s used in various industrial applications such as in the synthesis of pharmaceuticals, pesticides, and as a solvent in chemical processes.
