Manipulating models and building molecules in 3-dimensional space is the very best way for students to develop their spatial skills (one of the key issues in organic courses) and to get a real sense of how molecules are put together. To that end, we have done everything we could to make a model set available for students at a price they can afford. The model kit is particularly customized to the Solomons Fryhle text, but can be used with any of Wiley's organic texts. Manufactured by Darling Model Kits, this custom kit was designed by T.W.Graham Solomons. The kit consists of Darling's basic Molecular Vision kit with a few additional pieces, so that p orbitals could be shown in molecules like acetylene. This customized kit also has pieces that allow linear geometry for the sigma bonds of alkynes while also having orthogonal connections at each atom for the associated p orbitals. By attaching balls of the right colors it is possible to show the lobes of the p orbitals that make up the pi bonds in an alkyne. Ball colors can be matched symmetrically to show in-phase orbital overlap, or antisymmetrically to show an antibonding state. Use of colored balls with the appropriate framework geometry is a very nice feature of the Darling model set. Pieces from Darling's inorganic model set and are used for octahedral geometry.

Organic Chemistry, 13th edition provides a comprehensive, yet accessible, treatment of all the essential organic chemistry concepts, with emphasis on relationship between structure and reactivity in the subject. The textbook includes all the concepts covered in a typical organic chemistry textbook but is unique in its skill-development approach to the subject. Numerous hands-on activities and real-world examples are integrated throughout the text to help students understand both the "why" and the "how" behind organic chemistry.This International Adaptation offers new and updated content with improved presentation of all course material. It offers new material on several topics, including the relevance of intermolecular forces in the immune response and vaccines like those for Covid-19, the chemistry of breathing (carbonic anhydrase), how conjugation and complexation affect the color of lobsters, and how biodegradable polymers are used to stabilize vaccines and pharmaceuticals. Content is revised to reflect the current understanding of chemical processes, and improved depictions of longstanding mechanisms. This edition builds on the ongoing pedagogical strength of the book with the inclusion of additional worked and end-of-chapter problems and an engaging set of new problems entitled "Chemical Consultant Needed". These draw from the primary chemical literature and give students experience of working with more complex, polyfunctional structures, and areas where key transformations take place.
