Hello,

It would be difficult to provide you all the imporatnt topics. If your query is about NEET preparation, then I would suggest you to first go through the NCERT books. Keep your concepts clear.

Here are some of the best boks of Chemistry-

NCERT Chemistry textbooks for Class XI and XII

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!
