Organic Chemistry Chapters for NEET 2025: Organic chemistry is vital for NEET 2025, with many questions coming from this area. Knowing the weightage of each chapter helps you plan your study effectively. The NEET syllabus includes topics from both Class 11 and 12, so it’s important to understand how marks are distributed among Physics, Chemistry, and Biology.
Before you begin studying organic chemistry, find out how many questions typically appear from this section. Focusing on high-weightage chapters will boost your exam performance and increase your chances of success.
Organic Chemistry is an essential part of the NEET syllabus, contributing significantly to the Chemistry section. Mastering the core concepts and understanding reactions thoroughly will help you excel in this subject. Below are the key Organic Chemistry chapters you need to focus on for NEET 2025:
1. Some Basic Principles of Organic Chemistry
This foundational chapter introduces you to the basic concepts, such as hybridization, structural representation, functional groups, and nomenclature. It also covers the types of organic reactions, which are essential for solving higher-level questions.
2. Hydrocarbons
Hydrocarbons include alkanes, alkenes, alkynes, and aromatic compounds. This chapter deals with their preparation, properties, and reactions. Pay close attention to mechanisms such as Markovnikov’s rule, anti-Markovnikov addition, and the Friedel-Crafts reaction.
3. Haloalkanes and Haloarenes
Haloalkanes and haloarenes play a significant role in Organic Chemistry. This chapter covers their preparation, properties, and important reactions like nucleophilic substitution and elimination reactions.
4. Alcohols, Phenols, and Ethers
In this chapter, you’ll learn about the structure, preparation, and reactions of alcohols, phenols, and ethers. The chapter emphasizes reactions like dehydration of alcohols, esterification, and electrophilic substitution in phenols.
5. Aldehydes, Ketones, and Carboxylic Acids
One of the most critical chapters, this section focuses on the structure, preparation, and properties of carbonyl compounds. Understanding reactions like the Cannizzaro reaction, Aldol condensation, and the mechanism of nucleophilic addition is vital.
6. Amines
This chapter introduces amines, their classification, and properties. Important reactions like Hofmann degradation, Gabriel phthalimide synthesis, and reduction of nitro compounds should be studied thoroughly.
7. Biomolecules
Although this chapter is small, it carries significant weightage in NEET. Biomolecules include carbohydrates, proteins, lipids, and nucleic acids, which are vital for life. Carbohydrates provide energy, proteins are essential for cell structure and functions, lipids store energy and form membranes, while nucleic acids carry genetic information. Understanding their classification and the role of enzymes, which speed up biological reactions, is crucial for exams like NEET.
8. Polymers
This chapter deals with the classification, types, and preparation of polymers. It’s essential to understand the differences between addition and condensation polymers, along with examples like Bakelite, Nylon, and PVC.
9. Environmental Chemistry
Although not directly connected to organic reactions, this chapter emphasizes the environmental impact of various chemicals. Topics like ozone depletion, smog formation, and the effects of pesticides are important for NEET.
10. Chemistry in Everyday Life
This chapter focuses on the application of organic chemistry in daily life, including drugs, detergents, food preservatives, and artificial sweeteners. It’s important to understand the role of chemistry in health and the environment.

Skipping Organic Chemistry for NEET is not recommended. Organic Chemistry is a significant part of the NEET Chemistry syllabus, accounting for around 30-40% of the questions. Key chapters like Hydrocarbons, Aldehydes, Ketones, and Carboxylic Acids, and Haloalkanes and Haloarenes frequently appear in the exam. Without a good understanding of Organic Chemistry, you may miss out on crucial marks. Therefore, skipping it could impact your overall score.
Organic Chemistry in NEET covers several important chapters. Some of the key chapters include: Some Basic Principles of Organic Chemistry Hydrocarbons Haloalkanes and Haloarenes Alcohols, Phenols, and Ethers Aldehydes, Ketones, and Carboxylic Acids Amines Biomolecules These chapters cover essential topics like reaction mechanisms, functional groups, and organic reactions, which are crucial for scoring well in NEET.
For NEET 2024, the National Medical Commission (NMC) has removed several chapters from the Chemistry syllabus. These chapters include: States of Matter Hydrogen The s-Block Elements Environmental Chemistry The Solid State Surface Chemistry General Principles & Processes of Isolation of Elements Polymers Chemistry in Everyday Life While these chapters have been excluded, it is important to focus on the remaining topics that are essential for scoring well in NEET Chemistry. Always refer to the latest syllabus provided by NTA to ensure you're focusing on the relevant content.
Key organic reactions to focus on for NEET include: Wurtz reaction for the preparation of alkanes. Cannizzaro reaction for the oxidation of aldehydes. Aldol condensation for carbonyl compounds. Kolbe's reaction for carboxylic acids. These reactions are commonly tested and require conceptual clarity.
Organic Chemistry typically accounts for 14-18 questions in NEET Chemistry. The topics from Class 12 Organic Chemistry, such as Aldehydes, Ketones, and Carboxylic Acids, along with basic concepts like IUPAC nomenclature, often dominate this section.
Many students find Organic Chemistry challenging due to its vast syllabus and variety of reactions. However, with regular practice and thorough understanding of reaction mechanisms, the subject can be simplified. Consistency and smart revision techniques help in mastering Organic Chemistry for NEET.
