Compendium of Chemical Terminology, 2nd ed. In this context, the degree of hydrophilicity is measured by the contact angle, which can be simply stated as the angle formed when a droplet of water is placed on a surface, where a small angle (as seen from inside the droplet) means that the droplet has spread out over the surface, and that the surface is therefore hydrophilic. b. For this forum, the latter type of diagram would be better, I admit. They have a hydrophillic head and a hydrophobic tail. This is due to the electrons in the lone pairs being closer to the oxygen atom compared with the electrons in the O-H bonds. Although no such distinction between hydrophilic and hydrophobic nature of cation has been observed at higher concentration of AAILs, however, it is extremely important to visualize hydrophilic aspect of AAILs ions prior designing the green solvents for biocatalytic processes, enzyme immobilization, drug delivery and therapeutic applications. d. nitrogen, Suppose that an oxygen atom formed a chemical bond with another oxygen atom.
