Okay Let's assume u don't go for any coaching right ?? then in that case these books you should follow for organic :

NCERT (Do It Thoroughly) This will clear your fundamentals.

MS Chouhan (For Problems).

Dr R K Gupta.

These are the only books I would reccomend !!

For inorganic chemistry

NCERT Textbook (it's more than your ‘Bible’ for Inorganic Chemistry needed for PMTs). In fact, I can say that it will clear 85% of your needs in Inorganic Chemistry.

Concise Inorganic Chemistry for JEE Main & Adv. by JD Lee (yes, go for the JEE Edition, it will be really really helpful). Go for this book only if you feel that you are getting stuck while solving questions. So it's kind of an optional reference book.

NCERT At Your Fingertips by MTG for practice.

Previous Years' Question Papers with Solutions (it's 24 Years for AIIMS, 30 Years for NEET, and 15 Years for JIPMER). Alongwith this, please try to solve Last 15 Years' Question Papers of JEE Main (no need of JEE Adv.)

Hello ,

Chemistry is a very important in boosting your neet score .

Out of 45 questions asked in neet .

The weightage would be slightly more for organic then physical then inorganic

Also it is unpredictable. Depends can't say 

Assume  it's of equal .all parts are important.

So you need to focus on all three

As organic is important and tough

You have to buy supplement book for it definitely

Inorganic chemistry ncert should be sufficient

You also need to solve problems from physical so buy supplement
