General & Organic Chemistry Molecular Models

This basic molecular model set is ideal for biology, premed & nursing but has everything chemistry majors need too! Major functional groups you can build as well as amino, fatty, and nucleic acids or VSEPR theory structures for only $17.95 are listed below. This framework+discrete atoms style makes line drawings more intuitive especially when used with our 3D Molecular Model Builder.

• Standard colors: carbon (black); nitrogen (blue); oxygen (red); phosphorus (purple); etc.
• Discrete atoms (62) with elements easy to spot & number for stereochemical hierarchy
• Framework (ball-stick) style: match Fischer projections in book to physical structures
• Major functional groups: learn IUPAC naming conventions for organic compounds
• 121 bonds in 3 lengths; can be cut to scale to match atom radii if required

This student organic chemistry set offers all the benefits of our popular Molymod student Set but for a lot less $$. All the main VSEPR shapes from linear to octahedral can be demonstrated with the lone electron pair paddles that are included. 

The term framework model is sometimes used synonymously for both the Orbit 68845NV Basic Model Set & Darling Molecular Visions in educational settings, especially when showing the skeleton or backbone of larger molecules like hydrocarbons or polymers. However, "ball-and-stick" is more precise.

As a fundamental general, organic, and biological (GOB) chemistry molecular models set, the Orbit 68845NV aids learning of basic concepts and the physical & chemical nature of molecules. They are a cost effective complement to lab exercises for studying the geometry of organic and biomolecules. They can inform the correct use of subscripts & stoichiometric coefficients (the total number of molecules in a chemical reaction), the ratio between reacting species and the products formed in the reaction as it applies to conservation of matter.

As physical models, they can help clarify how chemical reactions involve atoms and molecules recombining into other molecules. Simple examples of this include rusting or how carbonic acid splits into carbon dioxide and water. These models can illustrate where a limiting reagent can act as a reactant limit that stops a chemical reaction. They can assist in the understanding the importance of balancing chemical equations by visualizing the breaking and forming of bonds on both sides. You can also use them to relate to line model chemistry for drawing skeletal structures & chemistry wireframe modelling.
