Hello,

To cover Organic chemistry, you should start with Basic of Organic chemistry. You can cover Haloalkanes and Haloarenes first. That chapter is Basic one. Then You can move for aldehydes chapter, then  Alcohol-chapter.

These two chapter is important as you have to remember the structure of atleast 4-5 example chemical compound.  Book have upto 10-20 but initially go for 5 atleast.

Then you can move toward amino, polymers, biomolecules. This almost covers organic chemistry of 11th class.  after covering it once, you can revise it like once in a day regularly so that you won't forget or get confused.

Make notes and read them. there must be end chapter excersie you can practice them too.  Refer OP tondon for question bank.

Hope it helps!
