What is the usual behavior of nonpolar molecules in water, and how can they be dispersed?
Instructor’s Answer: Non-polar molecules usually associate with one another when added to water. These cohesive interactions minimize the surface areas of interaction between individual water-molecules and the non-polar molecules. Stable dispersion of non-polar molecules in water is accomplished when an amphipathic molecule, e.g., phosphatidyl choline, forms a bridge between individual water molecules and individual non-polar molecules. Student A: The usual behavior of a nonpolar molecule can be described as hydrophobic or fear of water; due to the fact that a nonpolar molecule does not have a concentration of a charge whereas a polar molecule does. When a nonpolar molecule comes into contact with water, a polar molecule, the nonpolar molecule has a tendency to clump together or melt into each other, rather than react with the water. This phenomena, as seen in mixes of such substances as oil and water, occurs as a result of nonpolar attractions or Van Der Waals forces. The nonpolar mol
