Hello,

NCERT books of class 11th and 12th are important for NEET preparation. NCERT books will clear the basic concepts and lot of questions are asked from the NCERT books. I am mentioning few other important books which you can refer for preparation-

Physical Chemistry by OP Tandon
ABC of Chemistry for Classes 11 and 12 by Modern
Concise Inorganic Chemistry by JD Lee
Dinesh Chemistry Guide
Practise books by VK Jaiswal (Inorganic), MS Chauhan (Organic) and N Awasthi (Physical)

Hope this helps.

Good luck!
