CBSE Syllabus for Class 12 Physical Chemistry 2021-2022 Exam


Physical Chemistry is a special branch of Chemistry that deals with the principles of Physics involved in Chemistry. In Physical Chemistry, you study how matter behaves at a molecular and atomic level. You also study how chemical reactions take place and why they produce radiation and heat. Class 12 Physical Chemistry syllabus includes 5 Units - Unit 1: Solid State, Unit 2: Solutions, Unit 3: Electrochemistry, Unit 4: Chemical Kinetics and Unit 5: Surface Chemistry. It comprises 23 Marks out of the total 70 Marks in the theory examination. 


You must take note that Chemistry is further divided into different branches like Physical Chemistry, Organic and Inorganic Chemistry. CBSE provides a combined syllabus for Chemistry in Class 12. But, you must understand how different chapters of the Chemistry syllabus in Class 12 are related to its different branches. It will give you a better idea of the subject and will help in enhancing your interest in it. At askIITians you will find a complete list of Physical Chemistry topics included in the CBSE Class 12 Chemistry syllabus. We have also provided the marking scheme and exam pattern in the syllabus as per the latest CBSE guidelines for your convenience. 


Physical Chemistry is an important subject from a higher education perspective. In this subject, you will study how solids can be classified based on molecular forces between them, how to find the number of atoms per unit cell, band theory of metals and types of solutions. Electrochemistry is a separate branch of Physical Chemistry that deals with how atoms, electrons, and ions mingle in an electrical current. Unit 3 of your CBSE Chemistry syllabus 2021-22 includes a complete chapter on Electrochemistry where you will learn about the EMF of a cell, standard electrode potential, molar conductivity, laws of electrolysis, fuel cells and corrosion. 


Check Detailed CBSE Class 12 Physical Chemistry Syllabus 


Many students do not consider checking the CBSE syllabus during the academic year. But if that document had no importance then CBSE would not release the syllabus every year for the students. The syllabus helps you take note of all the topics that you have to study in the subject throughout the year. It also includes the marking scheme, list of practicals and internal assessment scheme. All this information is necessary for every student. It helps you understand the exam pattern more clearly hence reducing your exam fears and enhancing your preparation levels.

CBSE Class 12 Physical Chemistry Syllabus 2021-22 FAQs


#1 What are the chapters in physical chemistry Class 12?

Five chapters out of the CBSE Class 12 Chemistry syllabus are included in Physical Chemistry. These are Solid State, Solutions, Electrochemistry, Chemical Kinetics and Surface Chemistry. 


#2 Is NCERT enough for Physical Chemistry NEET?

It depends on how much time you have to prepare for NEET. If you are starting in Class 11, you can complete NCERT books for Class 11 Chemistry and Class 12 Chemistry and then practice higher-level questions from other books. But, if you have less time, then sticking to NCERT books is the best option. This is because:

  • NCERT books contain almost every topic that is given in the NEET syllabus. 
  • NCERT books contain easy to understand language and are good for enhancing your conceptual knowledge. 
  • You must practice all NCERT exercises thoroughly and prepare yourself for the NEET. 


#3 Can askIITians help me in preparing for Physical Chemistry in Class 12? 

Yes, of course! You can enrol in our online coaching classes and study regularly from our experts. We also have complete study materials for Class 12 Chemistry as per the latest CBSE guidelines. This includes chapter-wise notes, NCERT solutions, chapter tests, unit tests, practice papers, revision notes, mindmaps, flashcards and more! 


#4 How can I score full marks in Physical Chemistry in Class 12? 

  • You must study all the five chapters (Solid State, Solutions, Electrochemistry, Chemical Kinetics and Surface Chemistry) from NCERT Class 12 Chemistry book and make notes. 
  • Check previous year question papers and understand the pattern of questions asked from Physical Chemistry. 
  • Practice sample papers, mock tests, and assignments to memorise the topics in-depth. 
  • Solve numerical questions often so that you can get a good idea of how to deal with them in the exam. 
  • Use Physical Chemistry flashcards to memorise important topics, definitions and formulae.
