laboratory method of preparing alcohol

Laboratory method of preparing alcohol Hydrolysis of Alkyl Halides This is a nucleophilic  substitution reaction. R-X + KOHaq → R-OH The method is not satisfactory as olefins are also formed as by-products. However better yields is obtained by using moist Ag2O or aqueous K2CO3. Tertiary butyl halides mainly gives alkene due to dehydrohalogenation. Hydration of Alkenes This … Read more
