Ethanol Formula

  • Ethanol formula or ethyl alcohol is simple alcohol and is found in alcoholic beverages. Ethyl alcohol or ethanol is also represented as EtOH. The formula for ethanol and its structure is simple and is mentioned below with explanations.
  • It 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.

What is the Formula for Ethyl Alcohol or Ethanol?

  • The formula for ethyl alcohol or ethanol is .
  • Ethanol is a compound of carbon, hydrogen and oxygen elements was described by Antoine Lavoisier and its chemical formula was determined by Nicolas-Theodore de Saussure in 1808. Five years later, Archibald Scott Couper published the structural formula of ethanol.
  • Ethyl alcohol consists of two carbon chains, i.e.. , ethane from which a hydroxyl group is attached. The proper ethyl alcohol (ethanol) chemical formula and structural formula re given in the following points.

Ethyl Alcohol Chemical Formula

Ethanol has 2 carbon atoms, 5 hydrogen atoms, and an OH group. The chemical formula of ethanol is given by-

Formula for Ethyl Alcohol
  • Ethyl alcohol is a colorless, volatile liquid with a characteristic odor and a pungent taste. It has a flashpoint of , is classified as a depressant drug, and is toxic when ingested in large quantities.
  • The molecular formula describes the composition of ethanol molecules two carbon atoms six hydrogen atoms and one atom of oxygen occur per molecule but gives us no structural information. Structural information is how the atoms are connected and how the molecule fills the space.

Ethyl Alcohol Structural Formula

The carbon atoms in ethanol molecule are hybridized i.e.. , they have a free rotation. It is the second most simple alcohol and is represented as-

Ethyl Alcohol Structural Formula

There are various uses of ethanol and the most common one is in the pharmaceutical industry where it is used as an antiseptic. Apart from that, ethyl alcohol is also used in cosmetics, and in biotechnological industries.

Uses of Ethanol

  • Ethanol is used in alcoholic beverages, solvents, scents, flavorings, coloring, medicines, chemical synthesis, and thermometers.
  • Ethanol is used as a fuel an excellent solvent and an important raw material for making other chemicals. Pure ethanol is toxic liquid, methanol which is even more toxic is sometimes added to it to put off anyone wanting to drink it.
  • A mixture of ethanol and methanol is known as methylated spirits or sometimes ‘meths’ used in camping stoves.
  • Used as a raw material for making esters which in turn used as solvents in food flavoring, and in the manufacture of cosmetics.
  • Vinegar a weak solution of ethanoic acid is produced from ethanol by a biochemical process. It involves oxidation caused by bacteria called acetobacter.

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 of fermentation, which is the chemical breakdown of sugar by yeast.

Hand Sanitizers and 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

  • Do you ever wonder what the solvent is for products like perfumes, varnish, and paints? What these products have in common is that the solvent used is ethanol. 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.
  • 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.


Who Discovered Ethyl Alcohol?


Antoine Lavoisier described ethanol as carbon, hydrogen and oxygen compound, and in 1808 Nicolas Theodore de Saussure determined the chemical formula for ethanol, and in 1858 Archibald Scott Couper released a structural formula for ethanol.

Why is Ethyl Alcohol Flammable?


Ethanol is an alcohol created by an ethene-water mixture. Ethanol is flammable, as is the case with all carbohydrates, it will mix relatively well with oxygen to release carbon dioxide and water as waste products.

Why is Ethanol a Good Solvent?


Due to its hydroxyl (OH) group, ethanol is a very polar molecule with elevated oxygen electronegativity allowing for hydrogen bonding with other molecules. Ethanol can, therefore, function as a useful solvent and dissolve polar as well as non-polar substances.

What is the Percentage of Ethyl Alcohol?


A combination of ethyl alcohol and water is the ethyl alcohol used in fuels and nearly all industrial activities. Extremely toxic are both absolute and 95 percent ethyl alcohol.

What is Ethyl Alcohol Melting Point?


The melting point of ethyl alcohol is

What is the Formula for Ethanol?


What is the Reaction of Ethanol?

Metal salt formation


Alcohols are only slightly weaker acids than water, with a K a value of approximately The reaction of ethanol with sodium metal (a base) produces sodium ethoxide and hydrogen gas. This reaction is identical to the reaction of sodium metal with water.

What Are the Main Uses of Ethanol?


Ethanol is an important industrial chemical; it is used as a solvent, in the synthesis of other organic chemicals, and as an additive to automotive gasoline (forming a mixture known as a gasohol) . Ethanol is also the intoxicating ingredient of many alcoholic beverages such as beer, wine, and distilled spirits.
