In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. WebChapter 3 Alcohols, Phenols, and Ethers 2 3 Alcohols 4 The Hydroxy (—OH) Functional Group •The hydroxyl group (—OH) is found in the alcohol and phenol functional groups. (Note: that’s not the same as hydroxide, OH-, which is ionic.) –in alcohols, a hydroxyl group is connected to a carbon atom. –in phenols, —OH is connected to a benzene ring. ...
