Question -

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



Answer -

Ethanol undergoes intermolecular H-bonding due to thepresence of −OH group, resulting in the association of molecules. Extra energyis required to break these hydrogen bonds. On the other hand, methoxymethanedoes not undergo H-bonding. Hence, the boiling point of ethanol is higher thanthat of methoxymethane.
