The Engineering Chemistry course for undergraduate students is designed to strengthen the fundamentals of chemistry and then build an interface of theoretical concepts with their industrial/engineering applications. This book is structured keeping in view the objective of the course and is exclusively designed for the first-year engineering undergraduate students of Visvesvaraya Technological University (VTU). The book aims to impart to students an in-depth knowledge of various aspects of chemistry as applied to engineering. This textbook contains 9 chapters covering various disciplines of Engineering Chemistry and deals with various branches of chemistry such as - physical, inorganic, organic, and analytical - and extends the application of concepts to organic reaction mechanisms, stereo chemistry, etc. Other topics covered include electrode potential and cells, batteries and fuel cells, corrosion and its control, chemical fuels and photovoltaic cells, water and its treatment, instrumental methods of analyses, etc. About The Author Dr. K.
