Our Organic Chemistry kit is a modernized version of the original Brumlik Framework Molecular Model kit shown in our header.  We have updated to a clear plastic case that has integral hinges and latches and is slimmer to be more easily backpacked. It contains many tetrahedral clusters and Carbon (black) and Hydrogen (white) tubing needed for Organic Chemistry.  Enough tubing and clusters are included to make several five and six member rings simultaneously.  There are enough angles for making 6 pi bonds at once.  The number of clusters and tubing allows the student to prepare millions of different molecules.

Conformational Analysis

  The formation of carbon and heterocyclic ring structures are central to Organic Chemistry.  Understanding the three dimensional structure of these rings is called conformational analysis. Determining axial and equitorial positions as the ring's chair-boat-chair interconversion occurs, is always difficult to visualize.  1,3-diaxial interactions become apparent using our model kits as the determinant factor in the lowest energy conformation.  As students struggle to close 3 and 4 membered rings the concept of ring strain also becomes clearer.


 

Stereoisomers

    Students new to the three dimensional aspect of organic molecules can struggle with assigning R and S stereochemical designations for chiral Carbons.  The ability to build the molecule and actually rotate it so that the lowest priority group is away from you can often be enlightening to these students.  Determining if two molecules are enantiomers or diastereomers becomes easier with side by side comparisons.  Planes of symmetry can be more easily discerned for meso compounds.



Geometric Isomers

  This kit is ideal for building and comparing molecules of various geometries; for example, cis and trans and E and Z alkenes.  Double bonds are one of the strengths of our kits.  The way that double bonds are constructed makes it obvious to students how they affect molecular geometry and how the rotation about multiple bonds is restricted.
