And that is not a stabilizing effect because all these water molecules will essentially be fixed. They will be trapped around that non polar molecule and these water molecules will not be able to interact favorably with other water molecules. So when a non polar substance is added to water, the water molecules form a cage around that non polar molecule as shown in this diagram. This is not a favorable effect because it limits those water molecules, it traps those water molecules around the non polar substance and it limits the amount of hydrogen bonds that can form between these water molecules and that is not a favorable effect. Now, what happens if instead of taking one nonpolar substance we take two nonpolar molecules and place it into our water? What will happen now?
