Ethanol is ethyl alcohol or grain alcohol. It is the type of alcohol found in alcoholic beverages. Here's a look at its chemical formula. Answer: There is more than one way to represent the chemical formula of ethanol. The molecular formula is CH3CH2OH. The empirical formula of ethanol is C2H6O. The chemical formula also may be written as CH3âCH2âOH. You may see ethanol written as EtOH, where the Et represents the ethyl group (C2H5).
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected â¦ , with each atom represented by its chemical symbol.For example, oxygen's molecular formula is O2.or example: H2O2 is the molecular formula of hydrogen peroxide. In one molecule of hydrogen peroxide there are two atoms of hydrogen and two atoms of oxygen. This can be thought of as a 2:2 ratio of H:O. Reduced this ratio yields 1:1, and so the empirical formula is HO.
