Latest CBSE Chemistry Syllabus for Class 11
Chemistry Class 11 is the study of all the reactions that are happening around us in the world or inside our own body. Chemistry is also defined as “central science” as it bridges the gap between physics and biology, which further help us to understand the structure, composition and changes of matter. In other words, chemistry is the study of substances, their interactions, and the energy changes that accompany these processes.
For Class 11 students, chemistry is really important because it helps build a strong foundation for future careers. But, you’ll have to start from the ground, i.e. the basics of class 11 Chemistry. To know and prepare well, one should always have knowledge about their syllabus in depth so as to avoid any confusion and perform well in the examinations.
