which is a good book for 11 CBSE +JEE PREPARATION CHEMISTRY?

@sagar 
As you are in class 11^th , its the right time to start your JEE preparation , frst of all specially in chemistry , read ncert atleast 2 times , that will clear your concept and alongwith help u in school exams as well. 
and after ncert simoultaneously do the PHYSICAL CHEMISTRY by o.p tandon book and their problems , they are very very important , 
and for inorganic chemi , ncert is more than enough as jee ask every ques in inorganic from ncert , so, read ncert many times specially in organic , 
for inorganic additional to ncert u can solve the ARIHANT last 28 years jee questions , 
for organic , most vital is to prepare a list of name reaction and reagents , and read reaction mechanism from ncert and extra do some additional jee problem from morrision and boyd books . 
at the last phase u can take mtg publication books – final touch in inorganic chemi and reaction mechanism in organic chemi , they are helpfull . 
ASKIITIAN study package are also good , u can try that for some chapters , they will explain each and every concept precisely . 
HOPE IT CLEARS YOUR DOUBT 

ALL THE BEST ..
