CH2CH2OH2

CH2CH2OH2, more commonly written as CH3CH2OH, is the chemical formula for ethanol. It is a simple alcohol, with the chemical formula C2H5OH. Ethanol is a volatile, flammable, colorless liquid with a characteristic odor. It is produced industrially by the hydration of ethylene and by fermentation of sugars by yeast.

Ethanol is widely used as a solvent for other substances, in the production of beverages, in fuel, and as a feedstock for the synthesis of other chemicals. In beverages, ethanol is the intoxicating agent responsible for the effects of alcohol consumption. As a fuel, it can be blended with gasoline to create a biofuel. In industrial applications, its solvent properties make it useful in paints, varnishes, and cleaning products. It is also used as an antiseptic and disinfectant.

The production of ethanol through fermentation has a long history, dating back to ancient times. Modern industrial production methods are highly efficient, allowing for large-scale manufacturing. Ethanol's versatility and widespread availability contribute to its significant role in both industry and everyday life.
