NCERT Chemistry Class 11

NCERT books are the gold standard for both CBSE and competitive exams like NEET and IIT JEE. Chemistry is an essential part of the engineering entrance exams and medical entrance exams. Further, NCERT Chemistry Class 11 is divided into part 1 and part 2 and quintessentially introduces students to the fundamentals of Chemistry in a lucid language. The best thing about NCERT textbooks is that they do not merely focus on stating facts. Instead, they give a narration that pushes us to think, apply our imagination, and find solutions. This blog brings you a detailed breakdown of NCERT Chemistry Class 11 syllabus along with useful guides and solutions.
