Final answer
The acceptable names for the given ether are ethoxyethane (IUPAC) and diethyl ether (common).
Step-by-step explanation
The International Union of Pure and Applied Chemistry (IUPAC) systematically names chemical compounds to provide a standardized nomenclature. In this case, the IUPAC name for the ether is derived from the alkyl groups attached to the oxygen atom. The compound consists of two ethyl (C₂H₅) groups linked by an oxygen atom, resulting in the IUPAC name ethoxyethane. This name precisely reflects the molecular structure according to IUPAC guidelines.
Common names, on the other hand, are often used in everyday language and may not strictly follow IUPAC rules. In this instance, diethyl ether is an acceptable common name. The term "diethyl" indicates the presence of two ethyl groups, while "ether" signifies the functional group connecting them. This common name is widely recognized and has historical significance as diethyl ether was commonly used as an anesthetic in the past.
In summary, ethoxyethane is the IUPAC name, providing a systematic representation of the compound's structure. Meanwhile, diethyl ether serves as a common name that reflects the compound's practical usage and historical context.
