Question

what is the common name for ch₃ch₂och₂ch₃?
select the correct answer below:
dimethyl ether
dietbyl ether
methylmethyl ether
ethylethyl ether

Explanation:

Ethers are named by identifying the two alkyl groups attached to the oxygen atom and then adding the word "ether". In the compound \(CH_3CH_2OCH_2CH_3\), the two alkyl groups are ethyl (\(CH_3CH_2-\)) groups. So, the common name is diethyl ether. Dimethyl ether would have \(CH_3-\) groups (\(CH_3OCH_3\)), methylmethyl ether is an incorrect non - standard name (not in line with ether naming conventions), and ethylethyl ether is just another way of saying diethyl ether (but diethyl ether is the more commonly used and standard common name).

Answer:

dietyl ether
