Alcohols, Phenols and Ethers

Download Q&A

The Alcohols, Phenols and Ethers chapter focuses on oxygen-containing organic compounds, highlighting how the –OH and –O– functional groups influence structure, reactivity, acidity/basicity, and applications. This section is designed for Class 11–12 students, undergraduate learners, and competitive exam aspirants, with strong emphasis on reaction mechanisms, comparative chemistry, and exam-oriented understanding.

In this section, you will study:

  • Classification and nomenclature of alcohols, phenols, and ethers

  • Methods of preparation – laboratory and industrial routes

  • Physical properties – hydrogen bonding, boiling point, and solubility trends

  • Chemical properties of alcohols – substitution, oxidation, dehydration, and esterification

  • Chemical properties of phenols – acidity, electrophilic substitution, and characteristic reactions

  • Chemical properties of ethers – cleavage reactions and stability

  • Distinction tests between alcohols, phenols, and ethers

  • Comparative reactivity – alcohol vs phenol vs ether

  • Mechanistic insights – SN1, SN2, E1, and E2 relevance

  • NCERT- and UG-aligned explanations, supported by reaction mechanisms, flowcharts, MCQs, and PYQs

The content is structured to build strong conceptual foundations, enhance mechanistic reasoning, and prepare students for school exams, NEET, JEE, CUET-UG, and undergraduate assessments.
