Organic Chemistry Chapters for NEET 2026: Full Syllabus, Weightage & Important Topics

Organic Chemistry is one of the most scoring yet challenging sections of the NEET exam. It tests not just memory but conceptual clarity, reaction mechanisms, and application skills. For aspirants preparing seriously, understanding the Organic Chemistry chapters for NEET 2026 is essential for smart planning and focused revision.

The Organic Chemistry Chapters for NEET 2026 contribute around 28–30% of the Chemistry paper, making it a decisive section for rank improvement. Here, we covered the complete organic chemistry syllabus for NEET 2026 with chapter-wise list, most important topics, and weightage trends based on previous exams.

Organic Chemistry for NEET 2026

Organic Chemistry for NEET 2026 is strictly based on the NCERT Class 11 and Class 12 Chemistry textbooks. Most direct questions are framed from NCERT reactions, named reactions, and theory lines. Unlike Physical Chemistry (formula-based) and Inorganic Chemistry (memory-based), Organic Chemistry requires:

• Strong conceptual understanding

• Practice of reaction mechanisms

• Familiarity with functional group transformations

• Command over NCERT examples and exercises

Students often find Organic Chemistry difficult initially, but with proper sequencing and regular revision, it becomes one of the highest-scoring sections.

The NEET paper usually includes:

• 12–14 questions from Organic Chemistry

• A mix of direct theory, reaction-based MCQs, and multi-step conversions

• Questions from both Class 11 and Class 12 Organic Chemistry

Organic Chemistry Syllabus for NEET 2026

The organic chemistry syllabus for NEET 2026 focuses on reaction chemistry, functional group transformations, and biological relevance. Major syllabus areas include:

• IUPAC nomenclature

• Structural isomerism

• Hybridization and bond formation

• Reaction intermediates (carbocations, carbanions, free radicals)

• Types of reactions: substitution, elimination, addition, oxidation, reduction

• Preparation and properties of organic compounds

• Biomolecules like carbohydrates, proteins, and nucleic acids

• Synthetic polymers

• Drugs and chemicals used in daily life
  
  

NEET does not test advanced Organic Chemistry beyond NCERT, but it tests fundamentals deeply. Many questions are repeated conceptually every year.

Important Organic Chemistry Chapters for NEET 2026
