Engineering Chemistry is designed as a textbook for first year undergraduate engineering students. Besides covering the revised AICTE syllabus, it fulfils the syllabus requirements of universities across India. Divided into two parts, the book provides a comprehensive discussion of all relevant and important topics related to basic and applied chemistry.
The book is divided into two parts-part 1 covers core chemistry topics in 12 chapters and includes chapters on atomic and molecular structures, periodic properties, thermodynamics, chemical equilibrium, and phase rule. Part 2 covers applied chemistry topics such as water chemistry, corrosion, metals and alloys, polymers, engineering materials, and environmental and green chemistry.
The concepts are explained using numerous diagrams and solved examples. The chapter-end pedagogy includes summary, glossary, MCQs, and review questions and numerical problems.
