I have both the books for physical chemistry. I know for numericals P. Bahadur is recommended but what about the theory? Which book do you recommend ?

for a complete package rk gupta is quite good

well both are good but i recomend you the best book i have ever use is rc mukher ji even i also have both book but when my teacher recomend me rcm then i found that there is no need of theory outside rcm it is the best book after completing rcm you can solve maximum problem.........!!

i m also like u trying various book to study theory.. but its wastage of time your physical will strong when you practice more and more question...!!!

                                        thanks bro try hard... 

For theory , no doubt NCERT is the best . You can also refer O P Tandon for theory in physical chemistry and Arihant for organic chemistry.
