CBSE Class11 Chemistry syllabus

chemistry class-11 syllabusCbse syllabus of chemistry class 11 is taken from the ncert book of chemistry that has been provided from the cbse board . The syllabus is made for the student for the class 11 to get a part of knowledge of chemistry. The syllabus of class 11 is totally different from class 10 . In class 11 we will understand the importance of chemistry in our daily life and how a chemical reaction take place. The syllabus that the cbse had made is the basic of chemistry . Chapter wise syllabus is divided into two parts part 1 and part 2. Part 1 that will come in your half-yearly exam and part 2 will come in final exams. So the portion of the CBSE class11 chemistry is not so hard but you all have to take care of all the chapters because this chapter will help you all in 12th board exams so don't take the chapters for granted as it is a basic of the chemistry. and we know that if the base is strong we can build a huge tower.Chemistry is not a hard subject just you have to take care of the exceptional that's all.
