Question

Give reason for the higher boiling point of ethanol in comparison to methoxymethane.

Chemical Equations/Structures

Solution

Ethanol undergoes intermolecular H-bonding due to the presence of −OH group, resulting in the association of molecules. Extra energy is required to break these hydrogen bonds. On the other hand, methoxymethane does not undergo H-bonding. Therefore, ethanol has a higher boiling point than methoxymethane.
