The National Eligibility Entrance Test (NEET) is a crucial gateway for aspiring medical professionals in India. Chemistry, one of the core subjects in the NEET 2025 exam, holds significant weight in determining a candidate’s overall performance. In light of the recent NEET Chemistry Syllabus 2025 updates, students need to understand the modifications and thoroughly tailor their preparation accordingly.
The revised NEET Chemistry Syllabus 2025 introduces a new topic, Electrochemistry, while eliminating ten previously included topics. This strategic shift aligns with chemistry’s evolving nature and emphasizes electrochemistry’s importance in various medical applications.
| Unit name | NEET Syllabus Deleted topics |
| Some Basic Concepts of Chemistry | General Introduction: Important and scope of chemistry |
| Atomic Structure | Atomic number, isotopes and isobars. Concept of shells and subshells, dual nature of light |
| Chemical Thermodynamics | Third law of thermodynamics- Brief introduction |
| Some p-Block Elements | Atomic number, isotopes and isobars, Concept of shells and subshells, dual nature of matter and light |
| Organic Compounds Containing Nitrogen | Cyanides and Isocyanides- will be mentioned at relevant places |
| Environmental Chemistry | Environmental pollution: Air, water and soil pollution, chemical reactions in atmosphere, smogs, major atmospheric pollutants; acid rain ozone and its reactions, effects of depletion of ozone layer, greenhouse effect and global warming-pollution due to industrial wastes; green chemistry as an alternative tool for reducing pollution, strategy for control of environmental pollution. |
| Polymers | Classification- Natural and synthetic, methods of polymerization (addition and condensation), copolymerization. Some important polymers: natural and synthetic like polyesters, bakelite; rubber, Biodegradable and non-biodegradable polymers. |
| Chemistry in Everyday Life |

Chemistry, being one of the core subjects, holds significant weightage in the overall NEET score. With the introduction of the updated NEET Chemistry Syllabus 2025, it is crucial for aspirants to arm themselves with the best study resources to effectively prepare for the exam.
Recommended NEET Chemistry Books
With the introduction of Electrochemistry and the elimination of ten topics, NEET Chemistry preparation strategies must adapt to these changes. Students should allocate dedicated time to mastering electrochemistry concepts while ensuring adequate coverage of the remaining topics.
The chapters with the highest weightage in NEET Chemistry are: Chemical Bonding and Molecular Structure: 20%, Organic Chemistry – Some Basic Principles and Techniques: 10%, General Organic Chemistry: 10%, Equilibrium: 8%, Redox Reactions: 8%.
Cracking NEET in 1 month is extremely difficult, but not impossible. It would require you to dedicate a significant amount of time and effort to your studies. You would need to have a strong understanding of the concepts, and be able to solve problems quickly and accurately. You would also need to be able to manage your time effectively during the exam.
The toughest chapter in NEET Chemistry varies from student to student. However, some of the chapters that are often considered to be more difficult include: Chemical Bonding and Molecular Structure: This chapter covers a wide range of concepts, and can be challenging to master. Organic Chemistry – Some Basic Principles and Techniques: This chapter introduces some of the fundamental concepts of organic chemistry, which can be difficult to grasp. General Organic Chemistry: This chapter covers a wide range of organic compounds and reactions, and can be overwhelming for some students.
Skipping organic chemistry for NEET is not advisable as it constitutes a significant portion of the syllabus, accounting for about 25% of the Chemistry exam questions. To excel in NEET Chemistry, it's crucial to start preparation early, create a dedicated study schedule, and focus on understanding the underlying concepts rather than memorizing facts. Regular practice with previous NEET papers enhances problem-solving skills and familiarity with the exam format. If difficulties arise, seeking help from teachers, tutors, or online forums is encouraged. Taking these steps will ensure a more comprehensive and effective preparation for the NEET exam.
