Hello,

Here is the name of the some important chapters of the chemistry;

• Chemical bonding and S-block in inorganic chemistry,
• Alkyl Hallide, Alcohol & Ether (Reaction Mechanism) in organic chemistry,
• Mole Concept & Thermodynamics and Thermochemistry in physical chemistry.

Hope this will help you. All the best.

All chapters are equally important because if you see at the previous years paper then you will find that almost all the chapters contains questions, few questions which come from same chapters such as chemical bonding, equilibrium, redox reactions and basic organic chemistry contains more questions but don't skip anyabecause questions will come from each and every chapter.
