Ethanol

Ethanol, also known as ethyl alcohol, is a clear, colorless liquid that is produced by the fermentation of sugars by yeasts. It is commonly used as a recreational drug, a solvent, a fuel, and in the production of alcoholic beverages.

Chemical Structure

The chemical formula for ethanol is C₂H₅OH. It has a hydroxyl (-OH) functional group, which makes it a type of alcohol.

Production

Ethanol is produced by the fermentation of sugars, such as those found in corn, sugarcane, or other plant materials. Yeasts are used to convert the sugars into ethanol and carbon dioxide through a process called anaerobic respiration.

Uses

Ethanol has a wide range of uses, including:

• Alcoholic beverages: It is the main psychoactive ingredient in alcoholic drinks.
• Fuel: It is used as a biofuel, either in its pure form or as a gasoline additive.
• Solvent: It is used in the production of varnishes, perfumes, and pharmaceuticals.
• Disinfectant: It is used as a disinfectant in hand sanitizers and cleaning products.

Environmental Impact

Ethanol can be considered a renewable fuel source, as it is produced from plant materials. However, its production and use can also have environmental impacts, such as deforestation and competition with food crops for land.
