Phenols are an important topic in organic chemistry and are often covered in JEE (Main+Advanced) crash courses. Here’s a brief overview of phenols to help you prepare for the exam:
- Phenols are organic compounds that contain a hydroxyl (-OH) group attached to a benzene ring.
- The general formula for a phenol is ArOH, where Ar represents an aromatic ring (such as benzene or a substituted benzene).
- Phenols are weaker acids than carboxylic acids but stronger acids than alcohols due to the resonance stabilization of the phenoxide ion (ArO-).
- Phenols can undergo various types of reactions such as electrophilic substitution, nucleophilic substitution, and oxidation.
Here are some important reactions of phenols that you should be familiar with for the JEE (Main+Advanced) exam:
- Bromination: Phenols can be brominated using bromine water (Br2 in water). The reaction involves electrophilic substitution of a hydrogen atom on the benzene ring with a bromine atom. The product is a bromophenol.
- Nitration: Phenols can be nitrated using a mixture of nitric acid (HNO3) and sulfuric acid (H2SO4). The reaction involves electrophilic substitution of a hydrogen atom on the benzene ring with a nitro group (-NO2). The product is a nitrophenol.
- Esterification: Phenols can undergo esterification with carboxylic acids to form esters. The reaction is catalyzed by an acid catalyst (such as sulfuric acid or hydrochloric acid). The product is an aryl ester.
- Oxidation: Phenols can be oxidized using a strong oxidizing agent such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). The product is a quinone.
It’s important to practice these reactions and understand their mechanisms to prepare well for the JEE (Main+Advanced) exam. Good luck with your studies!

Nomenclature of JEE (Main+Advance) Crash Courses Phenols
JEE (Main+Advanced) Crash Courses targeting phenols often cover the nomenclature of phenols, which is the process of naming and identifying these compounds. Here are some of the basic principles of phenol nomenclature:
- Naming the parent compound: The parent compound of phenols is benzene, which is a six-carbon aromatic ring. Phenols are benzene derivatives in which one of the hydrogen atoms has been replaced by a hydroxyl group (-OH).
- Using prefixes to indicate the position of the hydroxyl group: When there is only one hydroxyl group present in the compound, the prefix “hydroxy-” is used to indicate its position on the benzene ring. For example, if the hydroxyl group is attached to the second carbon of the benzene ring, the compound is named as ortho-hydroxybenzene.
- Using numbers to indicate the position of multiple substituents: If there are multiple substituents present on the benzene ring, the position of each substituent is indicated by a number. The substituent with the highest priority is assigned the lowest possible number. For example, if there are two substituents present, one on the second carbon and one on the fourth carbon, the compound is named as 2,4-dihydroxybenzene.
- Using common names for some phenols: Some phenols have common names that are widely used in industry and research. For example, the compound 2-hydroxybenzoic acid is commonly known as salicylic acid, which is used in the production of aspirin.
Overall, the nomenclature of phenols is an important part of JEE (Main+Advanced) Crash Courses targeting phenols, as it is essential for identifying and describing these compounds in a systematic way.
