Are ethanol and diethyl ether the same molecule? Organic Chemistry Nomenclature Naming Functional Groups 1 Answer anor277 Mar 10, 2017 Ethanol and diethyl ether are different molecules.......... Explanation: We represent ethanol as H3CCH2OH; ethyl ether is H3CCH2OCH2CH3. Ether, has a much lower normal boiling point, 34 ∘C, than that of ethanol, 78 ∘C. Can you suggest a reason why?
