Nomenclature: 2,4,6-trinitrotoluene (TNT) An explosive Nomenclature of some Aromatic Groups: Phenyl group = φ = Ph = C 6H 5 = Aryl = Ar = aromatic group. Phenols A phenol is a benzene ring with a hydroxyl group. This article provides the revision notes of the Alcohols Phenols and Ethers chapter of Class 12 for the students so that they can give a quick glance of the chapter. Common naming system: The simplest hydroxy derivative of benzene is a phenol. 1-Nomenclature of Phenols Phenols are compounds that have hydroxyl group bonded directly to benzene ring. They react with aqueous sodium hydroxide (NaOH) to form salts. In the case of substituted phenol compounds, the terms ortho (1,2- disubstituted), meta (1,3-disubstituted) and para (1,4-disubstituted) are often used as prefixes in the common names. Source-based nomenclature can be used when the can be monomer identified.
2-Physical Properties 1-The OH group of phenols allows hydrogen bonding to other phenol molecules and to water.
The term ‘pol yphenol’ coul d thus be used to deﬁne natu ral products Although many of the essential oils are terpenes, some are phenolic compounds, for example thymol from Thymus spp.
4. The prefixes o, m, and p … Benzyl = Bn = It has a -CH 2- (methylene) group attached to the benzene ring. The goal of the system is to give each structure a unique and unambiguous name, and to correlate each name with a unique and unambiguous structure. Phenols can also be divided into three classes which are monohydric phenols, dihydric phenols and trihydric phenols. These diazonium salts are highly reactive in nature.

It is a broad term, and includes any aromatic rings. Phenols constitute probably the largest group of plant secondary metabolites, varying in size from a simple structure with an aromatic ring to complex ones such as lignins. 1 3 NOMENCLATURE IN ORGANIC CHEMISTRY 1.
3) Preparation of Phenols from Diazonium Salts When we treat an aromatic primary amine with nitrous (NaNO 2 + HCl) acid at 273 – 278 K, we can easily obtain diazonium salts. Chapter 7: Alcohols, Phenols and Thiols .
