Principle of similarity compatibility 。 The hydrophilic group is polar and soluble in polar solvent water; The lipophilic group is non-polar and soluble in non-polar oil. There are strong hydrogen bonds between water molecules. Water molecules can not only provide hydrogen atoms for generating hydrogen bonds, but also can accept hydrogen atoms provided by other molecules due to the lone pair of electrons on the oxygen atom. Hydrogen bonds are the main binding force between water molecules. Therefore, all solute molecules that can provide or receive hydrogen for the generation of hydrogen bonds are "structurally similar" to water. Such as ROH (alcohol), RCOOH (carboxylic acid), R2C=O (ketone), RCONH2 (amide), etc.
