Chemistry is one of the most scoring sections of the BITSAT exam if you prepare strategically and focus on the right topics. For many aspirants, Chemistry can be a game-changer — with well-structured concepts and consistent practice, it can boost your overall percentile significantly. In this blog, we will guide you through the BITSAT 2026 Chemistry Important Chapters that you must focus on, backed by previous trends, latest patterns, weightage data, and essential topic lists. Whether you are just beginning your preparation or revising for the final exam, this guide will help you prioritize topics wisely and score high marks.
Introduction: Why Focus on Chemistry for BITSAT 2026?
The Birla Institute of Technology and Science Admission Test (BITSAT) is a highly competitive computer-based test for admission into BITS Pilani campuses. Chemistry in BITSAT is known to be concept-based yet scoring if approached correctly. Unlike Physics or Mathematics, many Chemistry questions are direct and require factual recall, concept clarity, and logical application — making this section one of the most scoring parts of the exam.
Unlike JEE Advanced or Main, BITSAT’s Chemistry questions are typically:
Less calculation-intensive
Often direct-concept based
Drawn from NCERT + some application-based scenarios
This means that the right chapter focus + smart revision can significantly help you score above average with less time investment compared to other subjects.
Understanding the BITSAT 2026 Chemistry Syllabus
Before diving into the BITSAT 2026 Chemistry Important Chapters, let’s breakdown the overall structure:
B. Chemical Physics
Basic concepts of Chemistry
Atomic Structure
Chemical Bonding and Molecular Structure

5. Polymers & Chemistry in Everyday Life (CIEL)
CIEL has a fixed pattern every year and questions are direct. Polymers, their uses, and typical real-life applications are frequently tested.
Chapter Wise Weightage (Trend Based)
Though BITSAT doesn’t publish official weightage, based on pattern analysis from previous years (2020–2025), here’s a general trend:
Topic Category | Approx. % of Questions |
Physical Chemistry | 35%–40% |
Inorganic Chemistry | 30%–35% |
Organic Chemistry | 25%–30% |
This suggests that a balanced preparation across all subjects is essential, but Physical Chemistry and Inorganic Chemistry combined carry the most weightage.
