Molecular Geometry, Bonding
and Balloons—Demonstration Kit
By: The Flinn Staff
Imagine! Use balloons to build amazing models of molecular shapes. Make a tetrahedron, an octagon or even a trigonal bipyramid. Simply tie balloons together with our specially designed multiple balloon holder to help students visualize the shapes of molecules and sketch their three- dimensional structures. Comprehensive instructions guide you through the process to construct every kind of molecular geometry predicted using VSEPR theory. The models are very quickly interchanged so that all struc- tures can be covered. The holder and balloons may also be used to illustrate hybrid orbitals and even sigma versus pi bonding in organic compounds. Concepts: Covalent bonding, VSEPR theory, hybrid orbitals, sigma and pi bonds.
Time Required: 25 minutes
Materials Provided: All the parts needed to assemble the balloon holder and enough balloons to create 15 models, along with detailed procedures, background information and complete Instructor’s Notes.
Molecules, Compounds and Formulas—Models
Demonstration Scale Molecular Models
These giant-sized molecular model sets are the finest demonstration models available. The models are easy to see, use, and understand. The following sets are made up of durable 2" diameter atom centers. Each ball is brilliantly finished for easy visibility and instant identification of the element it represents. The uniquely designed bond receptors allow the molecules to maintain structure while also allowing rotation of atoms around bonds. Two sets are available. Each set includes both rigid bonds and flexible bonds which allow the construction of double- and triple-bonded molecules. Each set also includes The Molecular Models User’s Guide—a 43-page illustrated guide to more than ten organic chemistry concepts and to the many facets of molecular model building. Organic Chemistry Demonstration Model Set:
Set is designed to illustrate fundamental organic chemistry. Components include: 50 rigid bonds, 16 flexible bonds, The Molecular Models User’s Guide and a selection of 32 atom centers as follows:
