NCERT Class 12 Chemistry: Important Points to Keep in Mind!

The transition from class 11 to class 12 is a crucial juncture in a student’s life. Make sure that you don’t deviate from the path of preparation and keep working hard in studies even during holidays, along with all the enjoyment. And in-case if you haven’t started with the syllabus of class 12 yet, then you better start now because in all of the exams that you’ll be appearing for in the coming academic year, all of them will comprise majority of the portion from class 12. It’s better to start off with a new topic instead of languishing in class 11 syllabus, of-course, you should continue your preparation of class 11 along-with it.

For chemistry, it is very important to allot sufficient time, as a lot of portion of it is theoretical and you must be clear with every concept involved. Irrespective of the board to which you belong to, whether CBSE or state board, it is very important that you refer NCERT textbooks during your preparations. This is because, for exams like JEE Mains, the syllabus is of NCERT and generally questions are centered on the content of it. To help you kick-start your preparations, I have discussed the syllabus and some important points that are related to NCERT Class 12 Chemistry.

NCERT Class 12 Chemistry textbook

NCERT Class 12 Chemistry is divided into two parts, Part-1 and Part-2.

  • Part-1 consists of chapters from Physical and Inorganic Chemistry.

  • Part-2 consists of chapters from Organic Chemistry.

A list of all the chapters in each part is given below:


  • Unit I: Solid State
  • Unit II: Solutions
  • Unit III: Electrochemistry
  • Unit IV: Chemical Kinetics
  • Unit V: Surface Chemistry
  • unit VI: General Principles and Processes of Isolation of Elements
  • Unit VII: p – Block Elements
  • Unit VIII: d and f Block Elements
  • Unit IX: Coordination Compounds

Part 2

  • Unit X: Haloalkanes and Haloarenes
  • Unit XI: Alcohols, Phenols and Ethers
  • Unit XII: Aldehydes, Ketones and Carboxylic Acids
  • Unit XIII: Organic compounds containing Nitrogen
  • Unit XIV: Biomolecules
  • Unit XV: Polymers
  • Unit XVI: Chemistry in Everyday life

I won’t expound on each of these topics, you’ll get all the necessary information on the sub-topics under each chapter in the textbook itself. Note that, all the topics are relevant and make sure you don’t neglect any of them, but depending on the exam you are going to appear for, every topic will have its own weightage, so try to prepare accordingly and give extra time and effort on chapters having higher weightage. Information on this can be obtained from the official examination guidelines or can be determined by analysing past year papers. You don’t have to take the efforts in doing these analyses though, you can find the analysis of various past year examination papers and the weightages being already done at

Physical Chemistry –

Physical chemistry of class 12 comprises of aforementioned Units I to V. To master this section, you must be thorough with all the laws and should have practised ample problems based on those. Questions from this chapters will be either numerical or conceptual- theory questions so focus on those. In chapters like solid state, solutions and surface chemistry, memorise all the formulae and understand the properties for different cases mentioned in the textbook. Electro-chemistry and Chemical Kinetics are two very important chapters for every exam. Solve all the questions at the end of each chapter, solve past year papers and you can find some more questions to practise at Toppr.

Inorganic Chemistry –

As far as JEE Mains and Boards are concerned, for inorganic chemistry, NCERT is the best book to refer. Be thorough with all the important reactions, molecular formulae, trends in properties, exceptions. as direct questions will be asked on those. P-block elements carries the highest weightage among all the three chapters and also is vast in comparison with the rest. Students tend to neglect inorganic chemistry assuming that they’ll cover it later as it consists of only mugging up part. But this is a false-notion, not all the questions from inorganic chemistry will be straightforward from textbook, you might have to think well and dig deep into concepts before answering, but once you get the concept to be used, the solution will be cakewalk. Questions from inorganic chemistry might seem tricky if you are not thorough with even one small topic or concept. If well-prepared, you can bank upon inorganic chemistry to ensure your security of marks.

Organic Chemistry –

Class 12 organic chemistry consists of elaborated explanation of the various functional groups that you studied in your class 11 organic chemistry. You need to understand the various mechanisms of reactions, laws and rules in order to be thorough with the reactions and compound formations. All the chapters in organic chemistry will deal with how the formation of a specific compound takes place and discusses the steps involved in the formation. Questions related to these are direct, both in JEE Mains and Boards, so it is vital to keep knowledge of all the various reactions in organic chemistry along with the theory behind it. The last three chapters are relevant as they are quite easy and you only have to read and study in these chapters, there aren’t many conceptual laws that you have to apply. In biomolecules, be thorough with the structures and theory of DNA and RNA, in polymers, make sure you learn the formation, molecular structure, properties and uses of all the polymers given in the textbook. Chemistry in everyday life consists of only factual stuff, mugging up that is generally the best way employed by students to score well in this chapter.

Try to focus on the theoretical concepts more at the initial stage and as you gradually progress, shift the focus on problem-solving. Practise each and every question that is there in the NCERT textbook and later when you are done with all, start solving previous year question papers and sample papers. You can always refer another book along-with NCERT but strictly use it as a reference book only for concepts that you are not able to grasp from NCERT.

All the best!
