This textbook has been designed to meet the needs of B. Sc. (Honours) First Semester students of Chemistry as per the UGC Choice Based Credit System (CBCS). Maintaining the traditional approach to the subject, this textbook lucidly explains the basics of Inorganic and Physical Chemistry. Important topics such as atomic structure, periodicity of elements, chemical bonding and oxidation- reduction reactions, gaseous state, liquid state, solid state and ionic equilibrium are aptly discussed to give an overview of inorganic and physical chemistry. Laboratory work has also been included to help students achieve solid conceptual understanding and learn experimental procedures
