Hi, I am looking at how molecules with hydrophobic and hydrophillic properties move and orientate themselves in water. If I have say a PFOS molecule... The hydrophobic part (the perfluoroalkyl group - the carbon chain) will move to the liquid surface but the hydrophillic part (the sulfonate part) will not want to go there. So will it go to the liquid surface at all? If I have many molecules what will their orientation look like? Will they be layered? It is hard to imagine. Any ideas as to what the orientation will look like or somewhere that has an image would really help. Thanks for any help.
