Alcohols and phenols are formed when a hydrogen atom in hydrocarbon, aliphatic and aromatic respectively, is replaced by a hydroxyl group (-OR group). In alcohols, -OR group is attached to Sp3 hybridised carbon. In phenols, -OR group is attached to Sp2 hybridised carbon. Alcohols and phenols are classified based on the number of -OH groups present. Compounds containing one -OH group are known as monohydride alcohols and phenols. The terms dihydric, trihydric or polyhydric are used, when the compounds contain two, three or more -OH groups, respectively. After studying this chapter alcohol, phenols and ethers, students can learn how to write the names of alcohols, phenols, and ethers according to the IUPAC system of nomenclature.
