Overview

According to present scheme of school education at Senior Secondary stage, chemistry emerges out as a separate discipline. The present chemistry course has been developed basically around the themes: Why do chemical reactions occur? What is the quantitative relationship among reacting constituents in a chemical reaction? How far and how fast will a chemical reaction proceed under a given set of conditions? Can we predict whether a chemical reaction will occur or not? What is the relation between the structure of a chemical substance and its functions/properties? In what way is a chemical reaction relevant for getting new types of substances and materials for daily life and chemical industries? Some interdisciplinary aspects have also been provided to make the course more meaningful and functional. This Chemistry Course has three parts, I and II consist of theory portion and part III is a practical manual. Part I and II of theory portion has eight modules. Part-I consists of five modules namely as : Some basic concepts of chemistry, Atomic Structure and Chemical Bonding, States of matter, Chemical Energetics, and Chemical Dynamics. Part-II consists of three modules namely: Chemistry of Elements, Chemistry of Organic Compounds, and Chemistry in Everyday Life. Each module is further divided into different lessons.

Chemistry is the study of substances, their makeup and applications. In fact it is the study of all materials and is vital to every aspect of our lives. Organic Chemistry, Inorganic Chemistry, Analytical chemistry and Biochemistry are the main branches of chemistry. The career options in chemistry are practically endless! However, employment options depend on how far the education, training and experience taken. A chemistry or biochemistry degree can lead to career paths in professions such as medicine, pharmacology, agriculture, chemical engineering, forensic science, etc. Some of the Important career opportunities after studying chemistry at senior secondary level is as Career opportunities in Petrochemical and Pharmaceutical industries Analytical chemist Clinical biochemist Forensic scientist Chemical development engineer Scientific journalist Toxicologist Teacher/Professor Quality controller Laboratory assistant Research associate/ Research assistant Career opportunities in Plastics and Polymer Industry Career opportunities in Textile Industry Biochemistry Biotechnology.
