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

(N/A) Ethanol $(C_2H_5OH)$ undergoes intermolecular hydrogen bonding due to the presence of the polar $-OH$ group,which leads to the association of molecules.
Extra energy is required to break these hydrogen bonds during the phase transition from liquid to gas.
On the other hand,methoxymethane $(CH_3OCH_3)$ is an ether and does not possess an $-OH$ group,so it does not undergo intermolecular hydrogen bonding.
Hence,the boiling point of ethanol is significantly higher than that of methoxymethane.
