Descrição
*Now includes a new student guide for Polyhedron Molecular Models to help students gain a deeper understanding of molecular structures!* A New Set of the Best Quality and the Best for Undergraduates (1) Hybrid sp3, sp2, and sp atoms are easily recognized. (2) P, S, Cl, and metal atoms are included. (3) The set has many carbon 28 sp3-C and 12 sp2-C atoms. So, it is possible to construct a variety of molecules as exemplified below. (4) Bond lengths are easily recognized by color. (5) Smooth conformational changes such as the cyclohexane ring-flip. (6) Formation of three-membered rings such as cyclopropane and epoxide. (7) Electronic orbital plates are useful for studying -molecular orbitals. For example, the Woodward-Hoffmann rule shown below can be demonstrated by using this set.
