• Hi aspirant...!

Hope you're doing great...!

So, with regard of you're query. Generally, the chemistry of 11th and 12th grades are classified into 3 types and those are:

• physical chemistry
• organic chemistry
• inorganic chemistry.

the inorganic and organic chemistry parts contain more weightage than compare to physical chemistry. so, I would like to say complete these parts firstly and you can get 60 marks easily in the chemistry.

Now I am listing down the chapters names that contain more weightage in these both organic and inorganic chemistry:

• S,P,D and f-block elements.
• hydrogen.
• chemical bonding.
• amines, polymers, biomolecules
• aldehydes, ketones
• haloalkane and haloarenes.
• chemistry in everyday life.
• introduction to organic chemistry.

If you're 100 percent perfect  in these chapters, then you can easily score more than 60 marks in mains..

Hope this will helps you...!

GOOD LUCK...!
