Explain why all classes of low molecular weight amines are water soluble. O Low molecular weight amines are basic enough to form alkylammonium cations in water. Once such cation is formed, the solubility of amine drastically increases. The polarity of low molecular weight amines is much greater than that of water, thus allowing the molecules of these amines to be freely distributed among molecules of water. O Low molecular weight amines are gases at STP and gases usually have high solubility in water. O All amines can form hydrogen bonds with water. Low molecular weight amines have small aliphatic portions, thus the hydrogen bonds to water are strong enough to allow the amines to
