Ethanol Has Higher Boiling Point Than Diethyl Ether Why

Ethanol has intermolecular hydrogen bonding where as diethylether does not have this kind of bonding.

Ethanol has higher boiling point than diethyl ether why. Ethanol has a characteristic alcoholic odor. The melting point of dimethyl ether is 141 c. In alcohols oh group is present as a functional group which is highly polar oxygen attracts shared electrons of o h bond and acquires partial negative charge hydrogen being less electronegative than oxygen acquires partial positive charge. Ethanol has an alcohol functional group oh while diethyl ether has an ether functional group an alcohol between to carbons.

Boiling point of dimethyl ether is 24 c. Boiling point of ethanol is 78 37 c. But in an aqueous solution the solubility is also related to hydrogen bonding. Since in the alcohol there is hydrogen bonding in the o h group it has a higher boiling point than the ether.

Water has an unusually high boiling point because of the hydrogen bonds between the h 2 o molecules. Dimethyl ether is a colorless gas at room temperature. For example ethanol ch3ch2oh and dimethyl ether ch3och3 are structural isomers but have different boiling points. As a result alcohols have boiling points that are much higher than alkanes with similar molecular weights.

The boiling point of ethanol is much higher than the boiling point of. See full answer below. Ethanol is a colorless liquid at room temperature with high volatility. So bp of ethanol is higher than diethylether.
