lets not make such hasty assumptions about chemistry and solubility here. simply being in a negative concentration situation doesnt necessarily mean the molecule is going to dissolve in water. many factors play a role including the nature of the molecules in question, temperature, pH, other molecules present, etc. dehydration synthesis often requires large amounts of energy to form stronger bonds. not every bond is alike, and different types of bonding have different activation energies. hydrogen bonding is particularly strong, and often takes more than just being out of concentration to cause them to break down. youre also misusing the nature of concentrations. concentrations relate more to the movement of molecules than they do the structure of molecules in this situation. things move from a high concentration to a low concentration, this is usually shown with synthetic membranes, but anyways. this is not to say that concentration doesnt drive chemical reactions, but in this particular case, molecular distribution would play more of a role than chemical processes.
