Book Description
Hard and Soft Acids and Bases Principle in Organic Chemistry deals with various phenomena in organic chemistry that are directly related to or derived from the hard and soft acids and bases (HSAB) principle. Topics covered range from chemical reactivity to displacement reactions, along with various HSAB principle applications. This text consists of 11 chapters and begins with a historical overview of the HSAB concept, followed by a classification of hard and soft acids and bases and their theoretical descriptions. The reader is methodically introduced to the stability of organic compounds and complexes; displacement reactions of HSAB; and the chemistry of alkenes, aromatic, and heterocyclic compounds. The reactivity of organophosphorus and carbonyl compounds; organosulfur compounds and other chalcogenides; and organoboranes is also considered. The book concludes with an evaluation of other applications of the HSAB principle, paying particular attention to solubility and protonation; carbenes and nitrenes; the organic chemistry of group IV elements; and the reactions of organohalides, Grignard, and related agents. This book is intended for senior undergraduates or graduate chemistry majors, as well as organic chemists who are not familiar with the HSAB concept.

Book Description
This textbook provides essential information for students of inorganic chemistry or for chemists pursuing self-study. The presentation of topics is made with an effort to be clear and concise so that the book is portable and user friendly. Inorganic Chemistry 2E is divided into five major themes (structure, condensed phases, solution chemistry, main group and coordination compounds) with several chapters in each. There is a logical progression from atomic structure to molecular structure to properties of substances based on molecular structures, to behavior of solids, etc. The author emphasizes fundamental principles-including molecular structure, acid-base chemistry, coordination chemistry, ligand field theory, and solid state chemistry -and presents topics in a clear, concise manner. There is a reinforcement of basic principles throughout the book. For example, the hard-soft interaction principle is used to explain hydrogen bond strengths, strengths of acids and bases, stability of coordination compounds, etc. The book contains a balance of topics in theoretical and descriptive chemistry. New to this Edition: New and improved illustrations including symmetry and 3D molecular orbital representationsExpanded coverage of spectroscopy, instrumental techniques, organometallic and bio-inorganic chemistryMore in-text worked-out examples to encourage active learning and to prepare students for their exams . Concise coverage maximizes student understanding and minimizes the inclusion of details students are unlikely to use. . Discussion of elements begins with survey chapters focused on the main groups, while later chapters cover the elements in greater detail. . Each chapter opens with narrative introductions and includes figures, tables, and end-of-chapter problem sets.
