This document summarizes information about alcohols, alkyl halides, ethers, and epoxides. It describes their structures, naming conventions, physical properties, industrial sources, and common laboratory preparation methods. For alcohols, it discusses primary, secondary and tertiary classifications. Common reactions include cleavage of the C-OH and O-H bonds. Alkyl halides are described as R-X compounds that are insoluble in water. Ethers have the general formula R-OR' and are named by identifying the two groups attached to oxygen. Epoxides contain a three-membered ring structure.
