Section 13: Alcohols, Phenols, Ethers and Epoxides179 Section 13: Alcohols, Phenols, Ethers and Epoxides 13.1 Nomenclature and Properties of Alcohols & Phenols 13.1.1 Nomenclature •Alcohols and phenols contain a hydroxyl (-OH) group. In alcohols, this group is attached to an alkyl chain; in phenols the group is attached directly to an aromatic ring. •In a manner similar to alkyl halides, alcohols may be classified as primary, secondary or tertiary. This is based on the number of groups attached to the carbon atom directly attached to the hydroxyl group •The nomenclature of alcohols is surprisingly straightforward – the hydroxyl group has priority (of the groups considered thus far). ○The parent chain is the chain which includes the hydroxyl group – the –e suffix of the parent name alkane is replaced by –ol.
