- Function and Applications:
With this molecular model set for demonstration you can construct more complex organic chemistry compounds. This makes it the perfect teaching and learning companion both for introductory AND higher level organic chemistry courses. Atom centers are easily visualized by students with their large 2 inch (5 cm) diameter and brightly finished enamel colors. Changing molecular structures is made easy with our specially designed bond receptors that continue to allow free rotation at the bond site after assembly.
