The boiling point of ethanol is significantly higher than that of its functional isomer, dimethyl et — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

Ethanol molecules are highly associated through strong intermolecular hydrogen bonding due to the highly polar $O-H$ bond. This requires significantly more thermal energy to separate the molecules compared to dimethyl ether, which lacks an $O-H$ bond and therefore cannot form intermolecular hydrogen bonds with itself.
