General chemistry textbooks are usually lengthy and present chemistry to the student as an unconnected list of facts. In inorganic chemistry, emphasis should be placed on the connections between valence shell electron configuration and the physical and chemical properties of the element. Basic Principles of Inorganic Chemistry: Making the Connections is a short, concise book that emphasises these connections, in particular the chemistry of the Main Group compounds. With reference to chemical properties, Lewis Structures, stoichiometry and spider diagrams, students will be able to predict or calculate the chemistry of simple polyatomic compounds from the valence shell configuration and will no longer be required to memorise vast amounts of factual chemistry. This book is ideal for students taking chemistry as a subsidiary subject as well as honours degree students.

: Pharmaceutical organic chemistry is an important part of Pharmaceutical Research and Development unit, since it involves preparation of novel or modification of already existing molecules to extract the therapeutic application of these molecules. This book deals with different types of experiments, where the major emphasis is given on various basic techniques of Organic chemistry like melting point, boiling point, crystallization, distillation, and calibration of thermometer. It also includes identification of organic compound of various functional groups from carboxylic acid, Phenols, ketons, aldehyde….etc, with specific reaction procedure and its chemical reaction. It also covers experimental methods consisting of the derivatives preparations of functional groups. The book also covers some Organic preparation /Synthesis of compounds with reaction, principle and mechanism These experiments are selected in such a manner that the reader should get a in depth knowledge about the medicinal chemistry practicals. All comments and suggestions will be received with gratitude. I am very much grateful to KLE Academy of Higher Education and Research, all my beloved teachers, parents, wife for their constant support and encouragement. Thanks to my daughters Ananya and Adhya, who are my stress relievers. I would like to express my heartfelt thanks to each and everyone who directly or indirectly helped me in compilation of this book Last but not the least I am very much thankful to all my students who are the inspiration for writing this book.

This book’s main objective is to decipher for the reader the main processes in the atmosphere and the quantification of air pollution effects on humans and the environment, through first principles of meteorology and modelling/measurement approaches. The understanding of the complex sequence of events, starting from the emission of air pollutants into the atmosphere to the human health effects as the final event, is necessary for the prognosis of potential risk to humans from specific chemical compounds and mixtures of them. It fills a gap in the literature by providing a solid grounding in the first principles of meteorology and air pollution, making it particularly useful for undergraduate students. Its broad scope makes it a valuable text in many related disciplines, containing a comprehensive and integrated methodology to study the first principles of air pollution, meteorology, indoor air pollution, and human exposure. Problem-solving exercises help to reinforce concepts.
