Hello,

As you have not mentioned for which exam and for which class or standard you want the chapter wise explanation for it is difficult to give an answer as the syllabus is not known.Please write in detail about which grade/class/standard/exam/board you want chapter wise explanations for.

But i recommend you to search on google as there there many private sites which offer the explanations.Also i recommend you to search on youtube as well as the video explanations would benefit you .

Hope this helps!
