Document Summary

Strongly polar compounds: provides a polar solvent without the reactivity of a hydroxyl group. They can hydrogen bond with compounds that have h-o and h-n bonds. Nonpolar substances are more soluble in ethers than alcohols: effectively solvates cations but not as well for anions. Since ethers are nonhydroxilic they do not commonly react with strong bases: grignard reagents can be used with ethers. Common ethers: diethyl ether, dme, thf, dioxane. Crown ethers: large cyclic polyethers that specifically solvate metal cations by complexing the metal in the center of the ring. Often helps polar inorganic salts to dissolve in nonpolar organic solvents: ex: in acetonitrile with 18-crown-6. Alkoxygroups: o-me = methoxy o-et = ethoxy. Epoxides: three membered cylic ethers: name the rest of the molecule and use epoxy as a substituent, giving the number of the two carbon atoms bonded to the oxygen atom. Ex: cis-2,3-epoxy-4-methoxyhexane: can also name them with oxirane as the root name.
