Ethers Hydrogen Bonding with Water
Can ether and water form hydrogen bonds
Ether can form hydrogen bonds with water. In ether molecules, oxygen atoms have lone pairs of electrons, while hydrogen atoms in water molecules have partial positive charges. Due to the difference in electronegativity, the lone pairs of electrons of oxygen and the hydrogen atoms of water molecules will produce electrostatic attraction, which is a hydrogen bond. For example, the common ether ($C_2H_5OC_2H_5 $), the oxygen atoms in its molecules can form hydrogen bonds with the hydrogen atoms in water molecules. This hydrogen bonding makes the ether have a certain solubility in water. However, compared with alcohols, the ability of ethers to form hydrogen bonds with water is relatively weak. Because the hydroxyl hydrogen in the alcohol molecule can directly participate in the formation of hydrogen bonds, and the ether needs the help of the lone pairs of electrons of the oxygen atom, the solubility of the ether in water is usually less than that of the same carbon number alcohol.
In summary, ethers can form hydrogen bonds with water, but their hydrogen bond-forming ability and resulting solubility in water are different from other compounds containing hydrogen donors or receptors.
