Organic Chemistry is one of the crucial topics that come under NEET 2027 Chemistry Syllabus, and it is necessary for students to have knowledge about various concepts and reactions related to each of the chapters of Organic Chemistry. There are certain Organic Chemistry Chapters for NEET 2027, which consist of basics of organic chemistry, hydrocarbons, halogen derivatives, oxygen derivatives, nitrogen derivatives, biomolecules, and Chemistry in everyday life. Students can also check the organic chemistry weightage NEET 2027 for past trends. But the number of questions may vary every year, so students must prepare the complete syllabus.

Preparation for the Class 11 and Class 12 organic chemistry chapters for the NEET exam can also provide the candidates with an idea about the order of study. Students need to prepare the basic concepts from the chapters of class 11 and then proceed to learn about the reactions in class 12. In addition to NCERT, candidates need to revise NEET organic chemistry named reactions, reaction mechanisms, and conversions. Solving previous years' questions will enable the candidates to identify the pattern of questions asked.
Examining the last year’s questions can be an effective way for candidates to gauge the significance of Organic Chemistry chapters in the NEET exam. But NTA has not assigned any number of questions for each chapter. This is because the question distribution may differ every year, and hence the importance should be treated as a guide only.
The following table contains the chapter-wise weightage for NEET Chemistry from past exams. Candidates may utilise the information to focus on preparation of their most important chapters while covering the entire Organic Chemistry syllabus.
Chapter Name | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | Total |
0 | 2 | 3 | 4 | 4 | 2 | 15 | |
2 | 2 | 4 | 2 | 1 | 0 | 11 | |
3 | 3 | 1 | 5 | 4 | 6 | 22 | |
1 | 0 | 1 | 2 | 2 | 3 | 9 | |
3 | 2 | 1 | 2 | 2 | 0 | 10 | |

Based on the latest syllabus and how past exams have actually gone, here's what matters most in NEET Organic Chemistry:
Chapter | Important Topics |
Purification and Characterisation of Organic Compounds | Crystallisation, sublimation, distillation, differential extraction, chromatography and qualitative analysis |
Some Basic Principles of Organic Chemistry | IUPAC nomenclature, isomerism, hybridisation, electronic effects, reaction intermediates and types of organic reactions |
Hydrocarbons | Alkanes, alkenes, alkynes, aromatic hydrocarbons, preparation, properties and important reactions |
Organic Compounds Containing Halogens | Preparation, properties, C–X bond, substitution reactions and environmental effects of important halogen compounds |
Organic Compounds Containing Oxygen | Alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids and important reactions |
Organic Compounds Containing Nitrogen | Amines, nomenclature, basic character, preparation, reactions and diazonium salts |
Biomolecules | Carbohydrates, proteins, vitamins, nucleic acids and hormones |
Principles Related to Practical Chemistry | Detection of nitrogen, sulphur and halogens, functional group tests and organic compound preparation |
There are 8 Organic Chemistry chapters considered for NEET 2027 in this classification. These include:
1. Some Basic Principles of Organic Chemistry
2. Hydrocarbons
3. Organic Compounds Containing Halogens
4. Alcohols, Phenols and Ethers
5. Aldehydes, Ketones and Carboxylic Acids
6. Organic Compounds Containing Nitrogen
7. Biomolecules
8. Chemistry in Everyday Life
Considering the trend of questions asked in the previous year, Hydrocarbons had the highest number of total questions in the above table, followed by Organic Chemistry: Basic Principles and Techniques and Aldehydes, Ketones and Carboxylic Acids.
It is suggested that candidates not ignore any chapters despite having low weightage. The number of questions may vary every year, hence, it is essential to complete the entire syllabus for NEET 2027 preparation.
Knowing which chapters belong to Class 11 and Class 12 can help candidates plan their preparation in the right order.
Class 11 Organic Chemistry Chapters | Class 12 Organic Chemistry Chapters |
Some Basic Principles of Organic Chemistry | Haloalkanes and Haloarenes |
Hydrocarbons | Alcohols, Phenols and Ethers |
Aldehydes, Ketones and Carboxylic Acids | |
Amines | |
Biomolecules | |
Chemistry in Everyday Life |
Students need to initially cover the basic portion of Class 11th and cover portions like nomenclature, isomerism, hybridisation, electronic effects, and reaction intermediates. Once students build this basic base, they can cover the Class 12th chapters.
Named reactions are an important part of Organic Chemistry preparation. Candidates should learn the reaction, reagents, conditions, products and basic mechanism instead of memorising only the reaction name.
Named Reaction/Mechanism | Chapter |
Aldol Condensation | Aldehydes, Ketones and Carboxylic Acids |
Cannizzaro Reaction | Aldehydes, Ketones and Carboxylic Acids |
Reimer-Tiemann Reaction | Alcohols, Phenols and Ethers |
Sandmeyer Reaction | Organic Compounds Containing Nitrogen |
Friedel-Crafts Alkylation and Acylation | Hydrocarbons |
Nucleophilic Substitution (SN1/SN2) | Haloalkanes and Haloarenes |
Grignard Reagent Reaction | Alcohols, Phenols and Ethers / Carbonyl Compounds |
Haloform Reaction | Aldehydes and Ketones |
Wolff-Kishner Reduction | Aldehydes and Ketones |
Clemmensen Reduction | Aldehydes and Ketones |
Begin With Some Basic Principles of Organic Chemistry because topics like electronic effects, resonance, reaction intermediates, and isomerism aid in comprehending the latter topics covered in upcoming chapters.
Study the NCERT textbook thoroughly and make notes of all Important Chemistry formulas, reactions, exceptions, and statements of fact.
Practice the IUPAC nomenclature and isomerism instead of studying them just before the examination.
Study reaction mechanisms along with the conditions in which a particular reaction takes place instead of memorising reactions separately.
Maintain a reaction notebook including reactions, reagents, products, and exceptions.
Practice NEET chemistry PYQs on a chapter-wise basis after completing every chapter.
Practice questions of Organic Chemistry, including reactions from various chapters.
Sticking with this around the NEET Chemistry chapter-wise weightage usually shows up as better scores when the actual exam comes around.
NCERT for Classes 11 and 12 remains the foundation since that's where most questions come from directly. A few extra books can add more depth and give more practice on top of that.
Combine NCERT with the right reference and practice books, and covering every topic while solving Chemistry problems gets a lot easier.
Book Name | Why It’s Good |
NCERT Chemistry Textbooks | Clear basics and important for NEET |
Modern’s ABC of Chemistry | Good for extra practice and revision |
Dinesh Chemistry Guide | Simple explanations and practice |
Organic Chemistry Practice Book | Lots of practice questions for NEET |
According to the previous year trends, Hydrocarbons, Basic Principles and Techniques of Organic Chemistry, Aldehydes, Ketones and Carboxylic Acids, Amines, Biomolecules, Alcohols, Phenols and Ethers, and Haloalkanes and Haloarenes require revision.
Nevertheless, weightage is more important than the selection of syllabus topics in revision. A student appearing for NEET 2027 needs to revise all the topics of the syllabus.
Organic Chemistry forms a significant part of the NEET Chemistry paper. As per the previous years' analysis, it covers about one-third of the questions in NEET Chemistry, but the exact ratio varies every year.
In NEET Chemistry, there are 45 questions carrying 180 marks. However, there is no fixed number of questions from Organic Chemistry, as specified by NTA. Thus, candidates need to study all three parts of Chemistry.
Students must build a solid base in naming, isomerism, hybridisation, and electronic effects. Once students have studied all the basics, they should move on to reaction mechanisms and then revise key reactions in every chapter.
Regular reading of NCERT, practice of reactions, solving previous year questions and mock tests can help in improving accuracy. Students should keep short revision notes for themselves and revise important reactions and reagents.
Frequently Asked Questions (FAQs)
