Boiling Point and Water Solubility It is instructive to compare the boiling points and water solubility of amines with those of corresponding alcohols and ethers. Now the liquid can absorb energy in the form of heat for quite a while until it gets to its boiling point. Caffeine has no stereoisomers as there are no tetrahedral structures with all different substituents preventing a chiral center See Figure 1.
