R'OH, or "R-OH," represents a class of organic compounds known as alcohols. In this notation, "R" signifies a hydrocarbon chain or group, while "OH" denotes the hydroxyl functional group. Alcohols are characterized by their ability to dissolve in water and their use in various applications, including beverages, solvents, and fuels. The properties of R'OH compounds vary based on the structure of the "R" group. For example, ethanol is a simple alcohol commonly found in alcoholic drinks, while methanol is used as an industrial solvent. Alcohols can also participate in chemical reactions, making them important in organic chemistry.
