Hydrogen bonding of ethanol
WebPractically no ethanol clusters were formed on the hydrogen-terminated silicon surface. These results indicated that the cluster formation involved hydrogen-bonding interactions between surface silanol groups and ethanol hydroxyl groups in addition to those between ethanol hydroxyl groups. WebThe hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water. Methanol, ethanol, n -propyl alcohol, isopropyl alcohol, and t - butyl alcohol are all miscible with water.
