in physical chemistry if u are preparing for jee mains then ncert will clears your mains if u practice each and every problem given at the exercise of the book , but for jee advanced u need some extra books .
in physical chemistry u required mainly the problem solving skills by using 2-3 formula at times .
for that i am recommonding the following .
1- PHYSICAL CHEMISTRY BY O.P TANDON (GRB PUBLICATION )
2- PHYSICAL CHEMISTRY BY P BAHADUR ( ITS A VERY GOOD BOOK ) FOR JEE ADVANCED .
3- PROBLEMS SKILLS IN PHYSICAL CHEMISTRY BY MTG PUBLICATION ( FOR TIPS AND TRICKS U NEED THIS BOOK )
BUT FROM 1 AND 2 choose any 1 and not the both , whatever books u are following complete it properly and donot pile up .
u can also refers to the askiitian study material for the same .
ALL THE BEST ..
