Physical Chemistry Chapters for NEET 2025: The NEET exam is a highly competitive national-level test that opens the doors for students aspiring to pursue medical and dental courses across India. Success in this exam requires a strong command over three core subjects: Physics, Chemistry, and Biology. Chemistry, in particular, plays a significant role in boosting scores, with Physical Chemistry being one of its essential branches. Understanding key concepts in Physical Chemistry, such as thermodynamics, equilibrium, and electrochemistry, can help students maximize their performance and improve their overall rank in NEET 2025.
Physical Chemistry Chapters for NEET Overview
A vital part of the NEET exam syllabus, physical chemistry carries a lot of weight for students hoping to do well in Chemistry. To improve their overall performance on the NEET 2024 exam, prospective medical students should concentrate on thoroughly understanding the chapters on physical chemistry. The three primary components of the NEET 2024 syllabus are Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. The concepts covered in Classes 11 and 12 formed the foundation of the previous year’s syllabus, but the new syllabus has undergone updates and changes, with some chapters being deleted.
One of the most difficult exams for medical admissions is the NEET, which demands a strong background in biology, physics, and chemistry. Candidates must respond to 45 of the 50 questions in the Chemistry part alone (35 from part A and 10 from Section B). Anyone hoping to do well on the NEET test has to comprehend and get ready for the Physical Chemistry chapters.

How to Score High in NEET Physical Chemistry
1. Understand the Concepts Clearly
Physical Chemistry is concept-driven, so focus on thoroughly understanding each topic rather than rote learning. Clear concepts make it easier to solve problems efficiently.
2. Practice Numerical Problems
Physical Chemistry involves many numerical questions. Practice a variety of problems regularly to enhance your problem-solving speed and accuracy.
3. Master Formulas and Equations
Memorize important formulas and equations as they form the backbone of Physical Chemistry. Create flashcards or maintain a formula sheet for quick revision.
4. Time Management
Allocate specific time for each chapter and problem type. During exams, avoid spending too much time on a single question; move on and return to difficult ones later.
5. Focus on High-Weightage Topics
Identify chapters with higher weightage, such as Thermodynamics, Electrochemistry, and Chemical Kinetics, and devote more time to mastering these topics.
6. Solve Previous Year’s Papers
Practice with past NEET papers to familiarize yourself with the exam pattern and types of questions asked in Physical Chemistry. This also helps in managing exam-related stress.
