best way and book for organic chemistry for neet

ADITYA KUMAR Student Expert 12th Jul, 2022

Hi


Your whole chemistry is divided into three parts :-

******* physical chemistry

*******  organic chemistry and

*******  Inorganic Chemistry

To score well, you will have to master all the three i. e physical, organic and inorganic which you can do following the below tips :-

-------------------)For physical chemistry first of all go through the chapter then make a list of all the formulas and important concepts in the chapter then go through the solved numericals to understand how the concepts learnt are applied to solve them and then go for unsolved questions

------------------) In inorganic chemistry, you basically have to  memorize things, show the best thing is read the chapter from NCERT and keep revising it at regular intervals , and practice lots of MCQs to increase your memory power after each chapter

-------------------) For organic chemistry ,  you don't need to directly mug up reaction , you meed to first understand them, what you need to do is first go through the reaction and then go through it mechanism as well which will help you to understand how the reaction proceeds and then write two- three times the reaction and its mechanism on your own and then practice questions based on the same and you need to follow this process for every reaction in organic.

------------------) Solve at least 80- 100 mcqs per chapter to master them

-------------------)Practice previous year question papers of your neet examination . Previous year question papers are the most important as it will let you know types of questions which are asked, also questions on the same concept are repeated very often so it will be of great help for you.

---------------------) Go through chapter-wise test and once you're done with the complete syllabus go through mock test series , it will let you know your weak areas so that you can work on them and improve your score

††††† BEST  books for neet Chemistry

**** NCERT Chemistry textbooks for Class XI and XII :- Ncert chemistry is really good for Neet, go through all the solved examples, intext questions and exercise questions.For inorganic chemistry no need to follow any book in addition to NCERT

**** Physical Chemistry by OP Tandon :- Best for practising and mastering numericals in physical chemistry

**** MS Chauhan (Organic) :- It is a great book to clear all your concepts regarding reactions in organic,their mechanism etc

For best books for neet visit :- https://medicine.careers360.com/articles/best-books-for-neet

††††† IMPORTANT CHAPTERS

The list of the most important topics or chapters which carry the highest weightage in NEET in your chemistry section is given below

**** Coordination Compounds- 9%

**** p-Block, d- and f-Block Elements- 9%

**** Thermodynamics- 8%

**** Equilibrium -6%

**** Chemical bonding and molecular structure-5%

**** Solutions- 5%

**** Organic Chemistry: Basic Principles & Techniques- 4%

**** Alcohols, Phenols and Ethers :-4%

**** Aldehydes, Ketones and Carboxylic Acids-4%
