Which of the following is the correct formula for ethanol?

The correct formula for ethanol is C2H5OH. This formula represents the molecular structure of ethanol, which is a simple alcohol comprised of two carbon atoms (C), six hydrogen atoms (H), and one oxygen atom (O). The presence of the hydroxyl group (-OH) indicates that it is an alcohol, and the formula showcases both the hydrocarbon backbone and the functional group typical of alcohols.

In further detail, each component in the formula contributes to the overall properties and classification of ethanol. The two carbon atoms are part of a two-carbon chain (ethane), while the five hydrogen atoms and one hydroxyl group complete the structure characteristic of ethanol. This composition is what provides ethanol with its distinguishing chemical properties, such as being a solvent and its use in alcoholic beverages.

Understanding this formula is essential for recognizing the structure and reactivity of ethanol, especially in contexts such as chemistry and biological applications, which can also be relevant in certain discussions related to funeral service education when considering embalming fluids and their constituents.
