Alcohols are organic compounds that contain hydroxyl (-OH) functional groups attached to a carbon atom. There are many different types of alcohols, each with their own distinct structures and properties. Some common synonyms for the word alcohols include ethanol, methanol, isopropanol, hexanol, and pentanol. Ethanol is a widely used alcohol and is commonly found in alcoholic beverages. Methanol, on the other hand, is a toxic alcohol that is commonly used as a solvent or fuel. Isopropanol, also known as rubbing alcohol, is commonly used as an antiseptic or cleaning agent. Hexanol and pentanol are higher alcohols that are commonly used in the production of fragrances or as solvents.
