Physical Chemistry by P Bahadur eBook One of the most sought after and reliable book in physical chemistry , P Bahadur , with many solved examples , variety of questions ,having varying difficulty levels ,nice explanation of concepts and tricks related to solving and mastering problems in JEE Chemistry. This was what I heard from other website.Since I have also used this book, I will share with you all what I feel about this book. Initially I was planning to use it as a main course book for Physical chemistry part. But with the due course of time I realized that I was not able to get a proper grip on the subject due to unclear basics. So I asked my tutor for the help and started using this book only for questions. As the pattern has changed ,so the theory and  the way you approach the question  must also change.Content given in P Bahadur is no doubt is good,but is not upto the mark with the theory required for JEE Chemistry, bea...
