Hello aspirant,

The chapter is too much easy to understand, don't worry, I will forward a link, so that your understanding stands much easy instead of tree diagram write them on your notes, and remember most important part of the information. All of them is not important. https://ncert.nic.in/textbook/pdf/kebo102.pdf . This is that pdf. Instead of directly going into tables, read the theory first. If still you cannot understand comment the same, I will definitely explain you then. :)
