NCERT Class 12 Chemistry Book Chemistry-I is the official textbook published by the National Council of Educational Research and Training (NCERT) for students studying under the CBSE board syllabus. This first part of the Class 12 Chemistry textbook provides the foundation for higher studies and competitive exams such as JEE Main, NEET, and NTSE. It explains concepts of physical chemistry and inorganic chemistry through structured chapters, simple examples, and illustrations based on the latest NCERT syllabus (2023-24 edition).
Students preparing for board examinations or competitive exams like NEET and JEE should thoroughly study Chemistry-I before moving to Chemistry-II. This book aligns with the NCERT curriculum and promotes conceptual understanding rather than rote learning—helping students score good marks and strengthen fundamentals for higher education in science and engineering.
