Our Organic Chemistry kit is a modernized version of the original Brumlik Framework Molecular Model kit.  The only changes made were to the case.  It is a clear plastic, has hinges and latches and is a bit larger than our General Chemistry kit but is still quite easily backpacked. See the photo to the right.  It contains more 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 is always difficult to see.  1,3-diaxial steric interactions become self evident using our model kits as the determinant factor in the lowest energy conformation.


 

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.



Geometric Isomers

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