What Changed in Alcohols, Phenols and Ethers for 2026-27 NCERT (Rationalisation Note)

The 2026-27 syllabus retains this unit but renumbered it from legacy Chapter 11 to Chapter 7. Only a few legacy sub-topics were trimmed.

Sub-topicStatus in 2026-27Notes
Classification, nomenclature, structureKeptCore section, unchanged
Preparation of alcohols (hydration, hydroboration, carbonyl reduction, Grignard)KeptCore section, all four routes retained
Preparation of phenols (haloarenes, benzenesulphonic acid, diazonium salt, cumene)KeptAll four industrial and lab routes retained
Acidity of alcohols and phenolsKeptResonance stabilisation of phenoxide retained verbatim
Kolbe's reaction and Reimer-Tiemann reactionKeptBoth named reactions retained with mechanism prompts
Williamson ether synthesisKeptLimitations with 3° alkyl halides emphasised
Electrophilic substitution on anisole / aryl alkyl ethersKeptFriedel-Crafts alkylation and acylation, nitration, bromination retained
Extended pharmacological uses and biological function of alcoholsTrimmedDiscussion shortened in the current 2026-27 syllabus; commercial alcohols section now one page

Students still using a 2022 copy are studying close to 2 extra pages of trimmed pharmacology, none of which now appears in the Board paper.

Alcohols, Phenols and Ethers Class 12 Chemistry NCERT Book PDF FAQs

Ques. Where can I download the Class 12 Chemistry Chapter 7 Alcohols, Phenols and Ethers NCERT Book PDF?

Ans. You can download the Alcohols, Phenols and Ethers Class 12 Chemistry NCERT Book PDF directly from this page. Both the Normal and HD versions are available and both are free, with no registration required.

Ques. Is the Alcohols, Phenols and Ethers chapter aligned with the 2026-27 NCERT?

Ans. Yes. The PDF reflects the current 2026-27 syllabus for Class 12 Chemistry. The chapter retains all six core sections on classification, nomenclature, structure of functional groups, preparation and chemical reactions of alcohols and phenols, commercially important alcohols, and ethers; only the extended pharmacology discussion on commercial alcohols has been shortened in the new edition.

Ques. How many pages is the Class 12th Chemistry Alcohols Phenols Ethers NCERT Book PDF?

Ans. The chapter runs roughly 34 pages including the 6 numbered sections, 11 intext examples, the summary, and the 33 end-of-chapter exercises.

Ques. How many marks does Alcohols, Phenols and Ethers carry in the CBSE Class 12 Chemistry Board exam?

Ans. Alcohols, Phenols and Ethers typically carries 6 to 8 marks in the Class 12 Chemistry Board exam, sitting in the upper band along with Electrochemistry, Chemical Kinetics, and Aldehydes/Ketones/Carboxylic Acids. The marks are usually split as one 3-mark conversion or mechanism question plus one 5-mark phenol-reactions case study.

Ques. Why was the chapter renumbered from 11 to 7?

Ans. The 2026-27 NCERT reduced the Class 12 Chemistry book from 16 chapters (across Parts I and II) to 10 chapters. Alcohols, Phenols and Ethers moved from old Chapter 11 to current Chapter 7 in this consolidation. The chapter content itself is largely retained; only the numbering changed.

Ques. Which intext examples in Alcohols, Phenols and Ethers are most important for Boards?

Ans. Examples 7.5 (Lucas test reactivity order), 7.6 (acid-catalysed dehydration of ethanol mechanism), 7.9 (Kolbe's reaction), and 7.11 (Williamson ether synthesis) are the highest-yield. Practise each at least twice before the exam.

Ques. Has any topic been removed from Alcohols, Phenols and Ethers in the latest NCERT edition?

Ans. No major sub-topic was fully removed. The extended pharmacological uses and biological function discussion of commercial alcohols was trimmed in the 2026-27 print; all six numbered sections and every named reaction (Kolbe, Reimer-Tiemann, Williamson, Lucas, Friedel-Crafts on anisole) are intact.

Ques. How long should I take to complete the Alcohols, Phenols and Ethers NCERT chapter?

Ans. A four-day plan of about 10 to 11 hours total is realistic: one day for classification, nomenclature, and structure; one for preparation and physical properties of alcohols and phenols; one for chemical reactions of alcohols and phenols; and one for ethers plus full revision. The Collegedunia multi-day study plan further up on this page breaks the hours down section by section.
