प्रश्न
Give reasons for the following : Boiling point of ethanol is higher in comparison to methoxymethane.
Advertisements
उत्तर
Ethanol forms intermolecular hydrogen bonds due to the presence of hydrogen attached to the electronegative oxygen atom. As a result, ethanol exists as associated molecules while methoxymethane does not. Hence, the boiling point of ethanol is higher than that of methoxymethane.
