Why does not hydrogen-bonding occur in diethyl ether?
Because there are no hydrogens bound to a strongly electronegative element in diethyl ether.
Hydrogen bonding occurs where hydrogen is directly bound to a strongly electronegative element, typically oxygen or fluorine. In these circumstances, the electronegative element polarizes electron density towards itself to give bond polarity, which can significantly contribute to intermolecular bonding. The normal boiling points of both water,
By contrast, in diethyl ether, while the
