Bonding in Electron-Rich Molecules Qualitative Valence-Bond Approach via Increased-Valence Structures By: Richard D. Harcourt Publisher: Springer Print ISBN: 9783319166759, 3319166751 eText ISBN: 9783319166766, 331916676X Edition: 2nd Copyright year: 2016 Format: PDF Available from $ 109.00 USD SKU 9783319166766 This second edition was updated to include some of the recent developments, such as “increased-valence” structures for 3-electron-3-centre bonding, benzene, electron conduction and reaction mechanisms, spiral chain O4 polymers and recoupled-pair bonding. The author provides qualitative molecular orbital and valence-bond descriptions of the electronic structures for primarily electron-rich molecules, with strong emphasis given to the valence-bond approach that uses “increased-valence” structures. He describes how “long-bond” Lewis structures as well as standard Lewis structures are incorporated into “increased-valence” structures for electron-rich molecules. “Increased-valence” structures involve more electrons in bonding than do their component Lewis structures, and are used to provide interpretations for molecular electronic structure, bond properties and reactivities. Attention is also given to Pauling “3-electron bonds”, which are usually diatomic components of “increased-valence” structures for electron-rich molecules.
