Thiols. , . and ethers. Nomencalture. of alcohols. Use the end . ol. Examples. . Hydrogen bonding in alcohols and phenols. Alcohols and phenols form hydrogen bonds, and hence they have relatively high boiling points. This also makes the lower alcohols miscible with water. As the R group becomes larger, the solubility of alcohols in water decreases dramatically.. Dr. Jerry King. December 6, 2016. Omaha, Nebraska. INSTRUMENTS AND ASTM.
