Short explanation
Alcohols are organic compounds characterized by the presence of the hydroxyl functional group (–OH). They can be represented in three different ways: the molecular formula, which shows the number and type of atoms; the structural formula, which illustrates the arrangement of atoms; and the displayed formula, which depicts all bonds between atoms. For example, ethanol can be represented as C2H5OH in molecular form, showing two carbon atoms, six hydrogen atoms, and one oxygen atom. Understanding these representations is crucial for identifying and working with alcohols in chemical reactions.
