CBSE Class 12 Chemistry 2026 Expected Difficulty Level; List of high-priority topics
CBSE Class 12 Chemistry 2026 is expected to be Moderate in difficulty, with more case-based and application-driven questions. Check the expected difficulty level, high-priority topics, weightage trends, and important chapters to prepare smartly for the CBSE Chemistry exam 2026.
CBSE Class 12 Chemistry 2026 examis officially scheduled for February 28, 2026. You must already be curious about the expected difficulty level and which chapters will carry more marks. If we carefully study the board papers from 2023, 2024, and 2025, one clear pattern appears - the upcoming paper is most likely to fall under a “Moderate” difficulty level. But moderate does not mean easy.
We have noticed that over the past few years,CBSE boardhas slowly moved away from pure memory-based questions. The board is now focusing more on concept application, analytical thinking, and case-study-based formats. The syllabus is still strictly NCERT-based, but the framing of questions is changing. Instead of asking direct theory like “define this” or “state that,” the board now asks “why does this happen?” or “how will this change if…?”
Also, nearly 95% of the previous Chemistry papers (2023-2025) were directly based on NCERT textbook examples, back exercises, and in-text questions. However, many of those familiar questions were slightly modified, especially the numerical ones. For CBSE Class 12 Chemistry 2026, you can expect more twisted example-based numericals and case-based MCQs.

CBSE Class 12 Chemistry 2026 Expected Difficulty Level
Check the expected difficulty level for CBSE Class 12 Chemistry 2026 below, analysed using the past 3 years:
Year | Overall Difficulty | Expert Analysis and Observations | Main Focus Areas |
|---|---|---|---|
2026 (Expected) | Moderate | The paper will focus on the application of concepts. Around 50% are expected to be case-based and practical in nature. Shift from "what" to "how/why" questions. | Problem-solving and case studies |
2025 | Moderate | The paper closely followed the official sample papers. Organic Chemistry was relatively easy and scoring. Physical Chemistry was time-consuming | Electrochemistry and Biomolecules |
2024 | Moderate to Tough | There were more case-based questions compared to previous years. Some numerical problems in Physical Chemistry were challenging. | Coordination Compounds and Ketones |
2023 | Moderate | The paper was well-balanced. Many Organic Chemistry questions were directly from the textbook, but required thorough knowledge of name reactions.. | NCERT basics and solution-based numericals |

CBSE Class 12 Chemistry 2026 High-Priority Topics
Based on previous years’ board trends, topper strategies, and subject expert reviews, the following chapters are considered high-priority topics for CBSE Class 12 Chemistry 2026.
Topic Area | Expected Weightage | Preparation Focus |
|---|---|---|
Solutions | 7 Marks | Numericals, colligative properties, graphs |
Electrochemistry | 9 Marks | Nernst equation, conductivity, cell EMF numericals |
Chemical Kinetics | 7 Marks | Rate law, order of reaction, integrated equations |
d & f Block Elements | 7 Marks | Oxidation states, colour, magnetic properties, trends |
Coordination Compounds | 7 Marks | IUPAC naming, isomerism, VB theory, magnetic moment |
Haloalkanes & Haloarenes | 8 Marks | SN1/SN2 mechanisms, elimination, conversions |
Alcohols, Phenols & Ethers | 8 Marks | Acidity order, reactions, named reactions |
Aldehydes, Ketones & Carboxylic Acids | 8 Marks | Carbonyl reactions, named reactions, conversions |
Amines | 6 Marks | Basicity order, diazotisation, Hofmann bromamide |
Biomolecules | 7 Marks | Structures, functions, classification |
Note: High weightage does not mean you ignore other chapters. It simply means these chapters consistently contribute more marks and require extra practice.

After talking to multiple prospective test takers, we have noticed that students expect the CBSE Chemistry exam 2026 to be more challenging because 50% of the questions will now be competency-based. This means there is a lot of focus on case studies and real-life chemistry scenarios. Many students are also feeling nervous about the Physical Chemistry numericals because they have become more application-oriented.
You should also note that many have described the recent Chemistry papers as "lengthy". Because of this, you must currently prioritise speed and practice with sample papers to ensure you can finish all sections within three hours.
