Ethanol is a chemical compound that is present in a lot of things we use on a daily basis, ranging from perfumes to alcoholic beverages. In this lesson, we will learn more about the formula, structure, and uses of ethanol.

Ethanol: Formula and Structure

Ethanol, also commonly referred to as ethyl alcohol, pure alcohol, grain alcohol, and drinking alcohol, is most known as the alcohol present in alcoholic beverages. Ethanol, which can also be abbreviated asEtOH, is a colorless liquid with a slight odor, and it is soluble in water. It is flammable and volatile, so it evaporates easily when left in an open container.

Ethanol's chemical formula is C2H6O. This chemical formula can also be written as CH3CH2OH or C2H5OH. It is made of nine atoms that include two carbon (C) atoms, six hydrogen (H) atoms, and one oxygen (O) atom.

Its chemical structure is illustrated in the following picture. Here, there is a methyl group (which is the CH3-), a methylene group (which is the -CH2-), and a hydroxyl group (which is the -OH) in the chemical structure.
Uses of Ethanol

Ethanol is such a simple chemical compound, but it has so many uses. It is used in antiseptics, household cleaning products, and even varnishes. 

Alcoholic Beverages

In adult social gatherings and parties, it will be highly likely that there will be alcoholic beverages. Ethanol is the alcohol that is found in our alcoholic beverages like beer, whiskey, and brandy. In alcoholic beverages, the ethanol is produced from the process offermentation, which is the chemical breakdown of sugar by yeast.

There are times when we are served 'flaming beverages', much like the illustration below. This is due to the fact that ethanol, which is present in the drink, is flammable.

Medical Wipes

We often see hand sanitizer dispensers in public restrooms. During the flu season, we also tend to carry a small bottle of hand sanitizer in our bags. Ethanol is effective in killing organisms like bacteria, fungi, and viruses, so it is no surprise that another common use of ethanol is that it is an ingredient in hand sanitizer gels. It is also used in medical wipes and at clinics and hospitals.

Various Solvents

ethanol is used as solvents for products like perfumes,varnish, and paints.Because it is easily mixed with water and many other organic compounds, ethanol makes an ideal solvent for these products. It is a common solvent in personal care products, like deodorants, hairsprays, and astringents. It is also found in food additives, like food coloring and flavoring. Paints, lacquers and varnish also have ethanol as one of their components.
