Chapter Overview
Alcohols are an important family of organic compounds. Monohydroxy alkanes contain one hydroxyl group, -OH, attached to an alkyl group. Ethyl alcohol, also called ethanol, is one of the most common alcohols and has the formula CH3-CH2-OH or C2H5OH.
This chapter explains the manufacture of ethyl alcohol, especially by fermentation of sugars and other industrial methods. Students also learn combustion of alcohols, where alcohols burn in oxygen to produce carbon dioxide, water and heat energy. This property makes some alcohols useful as fuels.
The chapter also discusses applications of alcohols as fuels, the role of ethanol in industries and the impact of alcohols on daily life. Ethanol is used as a solvent, fuel, disinfectant and chemical raw material. Students should also understand safe and responsible handling because alcohols are flammable and some alcohols can be harmful or toxic.
