Outline the difference between alcohol and ether functional groups. From sample formulas demonstrate that ether molecules are created from an alcohol hydrocarbon substitution on the hydroxyl hydrogen. Present nomenclature through examples. Discuss uses of ethers as solvents and in medicine. Introduce halogenated ether molecules which are safer to administer than the traditional diethyl ether molecules. Note boiling point differences between alcohols and ethers, due to one small atomic change.
