How does molecular structure affect entropy

WebA simple molecular model for the hydrophobic effect. To understand what happens if we add a hydrophobic solute to water we will first have a look at the conformational entropy of a water molecule in liquid water. With each water molecule surrounded by four nearest neighbors, we can approximate the geometry around each water molecule as a ... Webentropy as water molecules are liberated by the burying of nonpolar molecules to the center of the globular structure. Since proteins have nonpolar side chains their reaction in a watery environment is similar to that of oil in water. The nonpolar side chains are pushed to the interior of the protein allowing them to avoid water
