WebThe enigma of the hydrophobic effect —a combination of the cohesive nature of water (itself a function of the small size of water and its strong intermolecular hydrogen bonding) and van der Waals interactions between solutes—is capable of driving the formation of many supramolecular complexes in nature. Utilizing it therefore amounts to a change of … Webwill also see that the hydrophobic effect is part of a family of processes called “entropy driven ordering” and that the hydrophobic effect has nothing to do with bonds between hydrophobic molecules. This should sound a bit strange to you right now, but I am sure that at the end of the class it will all make sense to you.
