Chapter 11: Alcohols, Phenols and Ethers

Preparation, properties, reactions of alcohols and phenols. Acidic nature comparison. Williamson synthesis for ethers. Uses.

👉 Exam Tip: Distinction between alcohol and phenol (reaction with FeCl₃), Lucas test, and reactions with Na metal are important. Acid strength order: phenol > alcohol is a common comparison question.

Chapter 12: Aldehydes, Ketones and Carboxylic Acids

Nucleophilic addition reactions (Aldol, Cannizzaro), distinguishing tests (Tollens’, Fehling’s, Benedict’s). Carboxylic acid preparation and reactions.

👉 Exam Tip: Named reactions in this chapter (Aldol condensation, Cannizzaro, Hell-Volhard-Zelinsky) are very frequently asked in board and NEET. Tollens’ and Fehling’s tests for distinguishing aldehyde and ketone are guaranteed.

Chapter 13: Amines

Classification, nomenclature, preparation, properties, reactions, diazonium salts — preparation and reactions, azo dyes.

👉 Exam Tip: Basicity order of amines and Hinsberg’s test for classification are important. Diazonium salt reactions (Sandmeyer, Balz-Schiemann) are must-prepare for NEET.
