CBSE Class 11 Chemistry Deleted Syllabus 2026-27: What Has Actually Changed?
In the current scenario of “CBSE Class 11 Chemistry deleted syllabus 2026-27” turns up into a conflicting topic, where different sites naming different chapters and reactions are removed. Here’s what the official curriculum document actually confirms.
For students considering CBSE class 11 tuition for chemistry, this distinction is particularly important. A good study plan should be based on the official curriculum rather than an unofficial list of supposedly deleted topics.
Is Anything Officially Deleted?
The Chemistry curriculum for Classes XI-XII, 2026-27, sets out 9 theory units for Class 11, worth 70 marks, plus 30 marks for practicals. It does not present any of these nine theory units as deleted.
The current CBSE curriculum should be treated as the authoritative reference for what is included in the 2026-27 syllabus.
Unit-Wise Marks Distribution

4 | Chemical Bonding & Molecular Structure | 7 |
5 | Chemical Thermodynamics | 9 |
6 | Equilibrium | 7 |
7 | Redox Reactions | 4 |
8 | Organic Chemistry: Basic Principles & Techniques | 11 |
9 | Hydrocarbons | 10 |
– | Theory Total | 70 |
– | Practical Assessment | 30 |

The Two Formative: Only Topics
The curriculum names two topics with a different assessment status:
- s & p Block Elements
- The Gaseous State
Both s & p Block Elements and The Gaseous State are included in the 2026-27 curriculum and are assessed only formatively; they do not contribute to the summative assessment. The curriculum also includes relevant NCERT textual material for reference.
These topics are not deleted. CBSE explicitly includes them in the syllabus but states that they will be assessed only formatively and will not contribute to summative assessment.
Why the Confusion Online?
The confusion appears to come from differences between third-party syllabus summaries and the official curriculum. Some online lists may label topics as “deleted” based on their own interpretation of changes in the syllabus or assessment structure. However, the official CBSE curriculum explicitly identifies s & p Block Elements and The Gaseous State as formative-only topics rather than describing them as deleted. Where a third-party summary differs from the official curriculum, the CBSE document should be treated as the primary reference.
What Should Students Study?
- Treat the current curriculum document as your reference for what’s officially in the syllabus.
- Study from the prescribed NCERT Chemistry textbooks (Part I & II), alongside your school’s teaching material.
- Follow your school’s guidance on how each topic, including the formative-only ones, will be assessed internally.
- Don’t assume a topic is gone just because a summary online leaves it out – check the source.
If organising study time around this year’s syllabus feels difficult alone, Ziyyara’s online chemistry tuition for Class 11 works through the current curriculum unit by unit with a dedicated tutor.

FAQs
Q1. Has CBSE deleted any Class 11 Chemistry chapter for 2026-27?Â
The official 2026-27 Chemistry curriculum does not identify any of the nine Class XI theory units as deleted. It separately lists s & p Block Elements and The Gaseous State as formative-only topics.
Q2. What are the formative-only topics?Â
s & p Block Elements and The Gaseous State, both are named in the curriculum and assessed formatively rather than summatively.
Q3. Are these two topics deleted?Â
No. They are included in the syllabus with a different assessment status and are assessed only formatively.
Q4. If a sub-topic isn’t individually listed this year, is it deleted?Â
Not necessarily. The current CBSE curriculum is the authoritative reference for what is included in the syllabus. A third-party list should not be treated as proof that a topic has been deleted.
Q5. How many marks does Class 11 Chemistry carry?Â
70 for theory, 30 for practicals, across 9 units.
Q6. Where can I check the syllabus myself?Â
cbseacademic.nic.in → Curriculum → Curriculum 2026-27 → Chemistry.
Conclusion
The “deleted syllabus” confusion for Class 11 Chemistry 2026-27 appears to stem from how different sources interpret the curriculum and its assessment structure. The official curriculum lists 9 theory units and separately identifies two additional topics as formative-only, rather than presenting those topics as deleted.
For preparation, the curriculum document and NCERT textbooks remain the most reliable starting point. If you’re looking for CBSE Class 11 tuition for Chemistry alongside that, Ziyyara’s one-on-one online chemistry tuition is built around the syllabus as it currently stands.
