Alcohols, Phenols and Ethers: Class 12 Chemistry (CBSE) important questions and practice
Alcohols, Phenols and Ethers is chapter 7 of 10 in CBSE Class 12 Chemistry. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Classification and IUPAC nomenclature of alcohols, phenols and ethers
- Preparation of alcohols: from alkenes, carbonyl compounds, Grignard reagent
- Preparation of phenols: from haloarenes, benzenesulphonic acid, diazonium salts, cumene
- Physical properties: hydrogen bonding and boiling points
- Reactions of alcohols: esterification, dehydration, oxidation; Lucas test
- Reactions of phenols: Kolbe, Reimer-Tiemann, bromination, nitration; acidity of phenol
- Williamson synthesis and reactions of ethers
What examiners usually ask
- Explain why phenol is more acidic than ethanol but less acidic than carboxylic acids
- Write the mechanism of acid-catalysed dehydration of ethanol to ethene
- How will you convert phenol to salicylaldehyde (Reimer-Tiemann) and to salicylic acid (Kolbe)? Give equations
Exam tip
Name reactions (Kolbe, Reimer-Tiemann, Williamson, cumene process) carry 2-3 marks almost every year; write each with reagent, conditions and structural equations, and support the acidity order with resonance stabilisation of the phenoxide ion.
