Why the boiling point of ethyl alcohol is much higher than that of dimethyl ether though both have the same molecular weight?

Why the boiling point of ethyl alcohol is much higher than that of dimethyl ether though both have the same molecular weight? Correct Answer Ethyl alcohol shows hydrogen bonding

Alcohols have much higher boiling points than the comparable alkanes or the related ethers because molecules of alcohols can interact through hydrogen bonding while those of alkanes and ethers cannot. Thus, Ethanol has a higher boiling point (78℃) than dimethyl ether (−25℃) though they have the same molecular weight.
