Selected Topics in Chemistry

Book excerpt: Chemistry is a branch of science which deals with the preparation, properties, structures and composition of substances. The prominence of chemistry is well known. Knowledge of chemistry will help to understand the natural processes, geochemical concepts, biochemical reactions, and environment. Developments in chemistry lead the discovery of immense number of chemical compounds with great applications. Broadly, chemistry can be classified into three braches viz., inorganic, organic and physical chemistry. Inorganic chemistry deals the preparation, properties and structure of all elements and their compounds except carbon and its compounds. Organic chemistry studies the synthesis, structure and properties of organic compounds. Physical chemistry concerned the physical property of chemical compounds.
