Hello Aspirant,

Best class 11 chemistry books for JEE books are as follows :

*NCERT

*Organic Chemistry by O P Tondon

*Concept of Physical Chemistry by P Bahadur

*Concise Inorganic Chemistry by J D Lee

*Physical Chemistry by P.W.Atkins

Etc.

While preparing for exams like JEE you have vast syllabus to cover, buying many books can be pretty confusing at times, I'd advise you stick to NCERT while preparing and jeep your concepts clear while you can use side books for particular topics and questions solving.

Hope this helps!!
