Answer
The high boiling point of ethanol $(78.2^\circ C)$ compared to dimethyl ether $(−23.6^\circ C),$ though both having the same molecular formula $C_{2}H_6O,$ is due to Hydrogen bonding.Hydrogen bonding is observed when $H$ atom is attached to more electronegative $N, F$ or $O$ atom.
Ethanol molecules are associated due to hydrogen bonding. This results in higher boiling point.
However, hydrogen bonding is not possible in dimethyl ether.
