@ mohammed . 
as far as jee mains and advanced are concerned , then i will prefer physical chemistry by p bahadur , its level of ques is perfect acc to the jee level . 
but dnt go with r cmukherjee as it mainly focus on the theory part which is required for medical aspirants . 
so, better go with p bahadur , 
and n. awasthy is not that much nessary , 
p bahadur nd last 6 years paper can give you a good rank in jee . 
practice as many mock test as possible . 
ALL THE BEST ..
