The subject of Chemistry is intimately linked to the well-being of human kind. Every biological species and matter around them are composed of atoms and molecules which are fundamentally chemical in nature. They assign different functional attributes to matter made up of them.  How and why substances combine or separate to form other substances, how substances interact to absorb or produce energy, the logical explanation of all sort of question are obtained in chemistry. Chemistry revolves around the study of composition, structure and property of any matter.. 

The subject matter has been organized around the laws and principles of chemistry. The rate of development in this subject is too high. Keeping this in mind this course is developed, it is intended to cover the certain topics for the students of Class XI- Some Basic Concepts of Chemistry, Structure of Atom, Classification of Elements and Periodicity in properties, Chemical Bonding and Molecular Structure, States of Matter, Thermodynamics and Equilibrium. These chapters are divided into modules as per syllabus and each module will be having e-Content, video tutorial, Self Assessment questions and Weblinks. This is a 6 months course. Each week, one module containing e-text, video tutorial along with self-assessment and weblinks for extra study will be released.
