Hello Student,

Important chapters in chemistry for JEE Mains are as follows-

• Chemical Bonding and Molecular Structure
• Chemical Thermodynamics
• Electrochemistry
• Inorganic Chemistry ( most important part for jee main )
• Organic Chemistry( xiith class oganic chemisty is more imporant,full scoring )
• Polymers and Bio Molecules
• Environmental Chemistry
• Chemistry in Everyday Life

Hope it helped you

Thank you
