The NCERT Chemistry syllabus is divided into two parts and covers nine chapters. Some of the major topics you will study include

· Some Basic Concepts of Chemistry

· Chemical Bonding and Molecular Structure

· Thermodynamics

· Equilibrium

· Introduction to Organic Chemistry

There are not just chapters; there are concepts that will help you make sense of everything from why water boils at a certain temperature to how energy changes during a reaction. Apart from theory, there are also practical components. Chemistry is not just something you read about; you get to experience it hands-on in the lab. The experiments are simple but essential. They help to understand how chemical reactions work.
