검증된 단계별 안내1
Identify the structure of the ether: The image shows an ether with two alkyl groups connected by an oxygen atom. Count the number of carbon atoms in each alkyl group.
Determine the length of each alkyl chain: Both alkyl groups have four carbon atoms, indicating they are butyl groups.
Assign the common name: Since both alkyl groups are butyl groups, the common name of the ether is 'dibutyl ether'.
Assign the IUPAC name: In IUPAC nomenclature, ethers are named as alkoxy alkanes. The longer chain is considered the parent hydrocarbon, and the shorter chain is the alkoxy group. Here, both chains are the same length, so you can choose either as the parent. The IUPAC name is '1-butoxybutane'.
Verify the options: Compare the determined names with the given options to ensure they match the correct answer, which is 'dibutyl ether; 1-butoxybutane'.
