There are many books available… but what I found good and used are…
- H Pandey organic chemistry, GRB publication
- MS Chouhan problems in organic chemistry JEE (for AIIMS practicing from Level 1, match making and Ass-reason is enough, level 2 can be solved if you want to be damn strong at it ;))
- I also used Paula Bruice’s organic chemistry for better understanding.
Thanks for A2A!
