Abstract: A molecular model building set for the formation of models of molecules and compounds primarily in the field of organic chemistry is disclosed. The set includes dimensionally accurate model building members (10, 60) that are rotatable about their axes, and can be interconnected and/or interlocked to form specific molecular models. Model building members depicting a double molecular bond (80) and a triple molecular bond (90) are also provided and can be interconnected and/or interlocked with the model building members (10, 60). All of the aforementioned model building members (10, 60, 80 and 90) are formed from a polypropylene copolymer material resulting in the members being inherently flexible while retaining sufficient rigidity to depict strain in molecular bonding. Because of this flexibility, the rotatability of the members, and the manner in which the members can be interconnected and/or interlocked, models of all known molecules and compounds in the field of organic chemistry can be formed.
