Hey!There

I am mentioning some important chapters from organic,physical and inorganic chemistry from where questions frequently asked:

PHYSICAL CHEMISTRY: ATOMIC STRUCTURE, GASEOUS STATE,CHEMICAL AND IONIC EQUILIBRIUM, THERMODYANICS,SOLUTIONS, CHEMICAL KINETICS AND ELECTROCHEMISTRY..

ORGANIC CHEMISTRY-HYDROCARBON,ALCHOL ETHERS AND PHENOLS,ALDEHYDE,KETONE AND CARBOXYLIC ACID,AKLY AND ARYL HALIDES.

INORGANIC CHEMISTRY-PERIODIC CLASSIFICATION,CHEMICAL BONDING,P BLOCK ELEMENTS,D AND F BLOCK ELEMENTS..

I hope this helps..
