Book Description
Polar Covalence provides a detailed account of a successful approach to understanding chemistry from knowledge of atomic structure and the properties that result from this structure. This book discusses the nature of multiple bonds. Organized into 16 chapters, this book begins with an overview of the interrelationships of various basic atomic properties. This text then describes chemical bonding, which can only occur when the nuclei of both atoms can attract the same electrons. Other chapters consider the bond energy of multiple bonds, which can be determined by calculating the energy in the usual way as though the bonds were single but of the experimental length. This book discusses as well the reduction of the lone pair bond weakening effect through the formation of multiple bonds. The final chapter deals with the relative roles of principles and practice in the teaching of inorganic and general chemistry. This book is a valuable resource for chemists and students.

Book Description
The thesis focuses on the syntheses, structural characterizations and chemical bonding analyses for several ternary R–M–Ge (R = rare earth metal; M = another metal) intermetallics. The challenges in understanding the main interactions governing the chemistry of these compounds, which lead to our inability to predict their formation, structure and properties, are what provided the motivation for this study. In particular, the R2MGe6 (M = Li, Mg, Al, Cu, Zn, Pd, Ag), R4MGe10-x (M = Li, Mg), R2Pd3Ge5, Lu5Pd4Ge8, Lu3Pd4Ge4 and Yb2PdGe3 phases were synthesized and structurally characterized. Much effort was put into the stabilization of metastable phases, employing the innovative metal flux method, and into the accurate structure solution of twinned crystals. Cutting-edge position-space chemical bonding techniques were combined with new methodologies conceived to correctly describe the Ge–M, Ge–La and also La–M polar-covalent interactions for the La2MGe6 (M = Li, Mg, Al, Cu, Zn, Pd, Ag) series. The present results constitute a step forward in our comprehension of ternary germanide chemistry as well as providing a good playground for further investigations.

Book Description
Satya Prakash's Modern Inorganic Chemistry is a treatise on the chemistry of elements on the basis of latest theories of Chemistry. Initial chapters are devoted to the study of fundamentals of Chemistry such as structure of atom, periodic classification of elements, chemical bonding and radioactivity, to name a few. It further graduates to complex discussions not only on extraction, properties and uses of the elements but also on preparation, properties, uses and structure of their important compounds. Chemistry of elements and their compounds have been explained on the basis of their position in the long form of periodic table and their electronic configurations/structures. Special emphasis has been put on the discussion of the correction between the structure and properties of elements/ compound. The book caters to the requirements of Bachelor in Science (Pass) courses. With detailed discussion on several advanced topics, the students of Bachelor in Science (Honours) and Masters in Science would also find it extremely useful.

Book Description
General, Organic and Biological Chemistry, 4th Edition has been written for students preparing for careers in health-related fields such as nursing, dental hygiene, nutrition, medical technology and occupational therapy. It is also suited for students majoring in other fields where it is important to have an understanding of the basics of chemistry. An integrated approach is employed in which related general chemistry, organic chemistry, and biochemistry topics are presented in adjacent chapters. This approach helps students see the strong connections that exist between these three branches of chemistry, and allows instructors to discuss these, interrelationships while the material is still fresh in students' minds.
