Structures of JEE (Main+Advance) Intermediate Course Phenols
The JEE (Main+Advanced) intermediate course in phenols covers a range of different structures of phenols, which are aromatic compounds that contain a hydroxyl group (-OH) attached to an aromatic ring. The general structure of phenols is:
Ar-OH

Nomenclature of JEE (Main+Advance) Intermediate Course Phenols
The nomenclature of phenols is based on the International Union of Pure and Applied Chemistry (IUPAC) rules for naming organic compounds. In general, phenols are named by adding the suffix “-ol” to the name of the parent aromatic hydrocarbon. For example, phenol, which is derived from benzene, is named as benzeneol.
When there are multiple substituents on the aromatic ring, the positions of the substituents are indicated by numbers, with the hydroxyl group (-OH) always being assigned the lowest possible number. For example, 2-methylphenol, also known as o-cresol, is named as such because the methyl group is attached to the second carbon atom on the ring, while the hydroxyl group is attached to the first carbon atom:
CH3 | CH3 | OH | C6H4
If there are multiple hydroxyl groups on the same aromatic ring, they are numbered consecutively, with the prefix “di-“, “tri-“, etc., indicating the number of hydroxyl groups. For example, 1,2-dihydroxybenzene, also known as catechol, is named as such because it contains two hydroxyl groups attached to adjacent carbon atoms on the benzene ring:
HO | HO | C6H4
In cases where there are substituents on both the hydroxyl group and the aromatic ring, the substituent on the ring is assigned a lower number than the substituent on the hydroxyl group. For example, 4-methyl-2-nitrophenol is named as such because the methyl group is attached to the fourth carbon atom on the ring, while the nitro group is attached to the second carbon atom on the ring, and the hydroxyl group is attached to the first carbon atom:
CH3 | NO2 | OH | C6H4
Overall, the nomenclature of phenols follows the same basic principles as the nomenclature of other organic compounds, with the position and nature of substituents on the aromatic ring and the hydroxyl group being used to determine the name of the compound.
