Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 12 Chemistry mastery score. A few sample questions are shown below; sign in free to practise all 96.
Key concepts: Alcohols, Phenols and Ethers (Class 12 Chemistry)
This chapter covers the preparation, properties and reactions of alcohols, phenols and ethers, and the acidic nature of phenols.
- Classification & preparation
- Alcohols (–OH on sp³ C), phenols (–OH on aromatic ring) and ethers (R–O–R'); prepared from alkenes, carbonyls, haloalkanes (Williamson synthesis for ethers).
- Acidity of phenols
- Phenols are more acidic than alcohols because the phenoxide ion is stabilised by resonance; electron-withdrawing groups increase acidity.
- Reactions of alcohols
- Undergo dehydration to alkenes, oxidation to carbonyls/acids, and esterification with acids.
- Electrophilic substitution in phenol
- The –OH group is ortho/para directing and activating, so phenol readily undergoes nitration, halogenation and the like.
- Important reactions
- Kolbe's reaction (salicylic acid), Reimer–Tiemann reaction (salicylaldehyde), and Williamson ether synthesis.
💡 Exam tips for Alcohols, Phenols and Ethers
- Phenol is more acidic than alcohols (resonance-stabilised phenoxide) but less acidic than carboxylic acids.
- Use Williamson synthesis (alkoxide + primary haloalkane) for unsymmetrical ethers to avoid elimination.
Sample questions
Functional group of alcohol:
Hydroxyl group.
Phenol is more acidic than alcohol because:
Negative charge delocalised over benzene ring.
Williamson ether synthesis uses:
Best with primary halides to avoid elimination.
