Question

Select the common name for the other. The common name is: 1-methylbutyl ether butyl methyl ether methyl butyl ether O methoxyethane O

Answer 1

The common name for an ether is typically the names of the groups attached to the oxygen, followed by 'ether' (e.g., diethyl ether for CH3CH2-O-CH2CH3). Names vary if groups are different (e.g., methyl propyl ether) or when using IUPAC nomenclature (e.g., methoxyethane for CH3OCH2CH3).

Step-by-step explanation:

The common name for an ether is typically derived from the names of the groups attached to the oxygen atom, followed by the word ether. For example, if the molecule consists of two ethyl groups attached to the oxygen atom, like in CH3CH2-O-CH2CH3, the common name would be diethyl ether. In cases where there are two different groups attached to the oxygen, such as CH3-O-CH2CH2CH3 (methyl group and propyl group), the common name would be methyl propyl ether.

However, when naming ethers using IUPAC nomenclature, the smaller alkyl group and the oxygen are named together as an alkoxy group, and the remainder of the molecule is named like a base chain. For instance, CH3OCH2CH3 would be methyl ethyl ether in common nomenclature but is known as methoxyethane in the IUPAC system.
