National Eligibility Cum Entrance Test Phy. Chemistry Chapters
The NTA has officially released the syllabus for NEET 2025, clarifying which topics and chapters students need to focus on.
Physical chemistry is the most crucial of the three sections in Chemistry—physical, Organic, and Inorganic chemistry as it requires conceptual depth and extensive numerical problem-solving.
In NEET, the weightage given to Physical Chemistry is balanced between Class 11 and 12 chapters:
- Class 11 Physical Chemistry( 16-18% weightage): Important topics are Thermodynamics, Equilibrium, and Mole Concepts; each of which carries 2-3 questions
- Class 12 Physical Chemistry (12-14% weightage): Topics like Chemical Kinetics, Electrochemistry, and Solutions, carrying high marks come in 1-2 questions for each.
In the previous NEET exams, Physical Chemistry accounted for 15-18 questions (30-35% of Chemistry). Chapters like Thermodynamics, Equilibrium, and Chemical Kinetics had an average of 2-3 questions. Top performers got 85-90% of their Chemistry marks by doing well in numerical and NCERT concepts.
NEET Physical Chemistry Syllabus
The NEET Physical Chemistry syllabus consists of key topics from Class 11 (mole concept, thermodynamics, equilibrium) and Class 12 (chemical kinetics, electrochemistry, solutions). It will focus on conceptual understanding as well as problem-solving skills with an emphasis on numerical and real-life applications.
