Explain what happens when nonpolar molecules are dropped into water.
When nonpolar molecules are dropped in water, the water forms cages around them, hoping to hydrogen bond. However, the molecules can't hydrogen bond. And so, they instead disrupt the hydrogen bonds that were formed earlier.
Because water doesn't know what to do, it surrounds the nonpolar molecule. At this point, the nonpolar molecule has a higher surface area exposed to water and the water has less hydrogen bonds formed. This is not a favorable condition. As a result, the nonpolar molecules seek one another out to reduce their surface area; and, water facilitates this by pushing the hydrophobic molecules together, thus maximizing their hydrogen bonding and minimizing the nonpolar molecule's surface area
