 * ﻿Ethers are unable to form hydrogen bonds with water. It does not take much energy to separate either molecules from one another.
 * This is why their boiling points are low and can easily evaporate.
 * Diethylether
 * Diethylether was discovered in the 1800's. It was used as the first anesthetic in surgery.
 * Amines
 * Amines are organic compounds where their nitrogen atoms are bonded to one, two, or three carbons.
 * Because of the nitrogen-hyrdorgen bond it is not very soluble in water and has a low boiling point.
 * Amines have a fowl oder like the smell of a decaying human or animal.
