NEET Organic Chemistry Syllabus 2025, Check Important Topics with weightage

NEET Organic Chemistry Syllabus 2025: Organic Chemistry is one of the most significant and high-weightage areas in NEET UG 2025. The NEET Chemistry syllabus is divided into three sections: Physical, Inorganic and Organic Chemistry. Over the years, as questions are frequently asked from this section, students must strategically prepare the topics included in the NEET Organic Syllabus 2025. To make things simple for the students, we have also shared the List of the most important chapters of Organic chemistry along with a detailed syllabus on this page.

NEET Organic Chemistry Syllabus 2025

In the NEET Chemistry Section, the Organic Chemistry presents several questions. Key topics, including reaction procedures, named reactions, and functional groupings, can boost marks. Organic Chemistry typically accounts for 20-28% of the NEET exam’s overall Chemistry marks. Organic Chemistry makes up around 15-20% of the 45 Chemistry questions on the exam. This proportion remains consistent year after year, making it a crucial component of the Chemistry course.. Knowing the NEET Organic Chemistry Syllabus 2025 and important topics in each chapter might help you prepare more effectively for achieving high NEET exam scores.
