I hope you are having a good day.

First of all this is a chemistry chapter and it's not easy to explain the whole chapter here itself. This one chapter cover a wide range of informative topics under it and these topics can not be explained here.

You can clear your concepts by looking through the educational videos provided by different teachers on Youtube. There you have a great chance of understanding all the concepts related to this topic.

Hope this would help you. Wishing you for the best.
