Can a molecule be both hydrophobic and hydrophilic? I think that's what soap (alkali salts of fatty acids)is all about. One end of these molecules attach to water molecules, the other end rejects water.(attaches to itself if ot â¦ her molecules of alkali salts of fatty acids are near by.)
A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents.nother example is soap, which has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively.
