Phenols are organic compounds characterized by a hydroxyl group (-OH) directly attached to a benzene ring. For NEET preparation, focus on their structure, acidity, reactions, and nomenclature, particularly comparing them to alcohols and ethers.
- Comparison with Alcohols and Ethers:Phenols are more acidic than alcohols due to the resonance stabilization of the phenoxide ion. Ethers, where oxygen is bonded to two alkyl/aryl groups, are less acidic than both alcohols and phenols.
