Ethanol and dimethyl ether have the same molecular formula, i.e. C2H6O. Their structural formulas are CH3CH2OH (ethanol) and CH3OCH3 (dimethyl ether). Draw the Lewis structure of each molecule and describe the intermolecular forces for each one. One of them has a boiling point of -23.7 oC, the other has a boiling point of 78.4 oC. Match the boiling points to the substance, justifying your answer.
