Some Reflections on the Use and Abuse of Molecular Models
Petersen, Quentin R.
J Chem Educ, 47, 1, 24-29, 70 Jan
Describes the historical applications of molecular models and the controversies which they produced. The author discusses types of molecular models from the van't Hoff and Kekule models to the more recently developed ones. He presents a new model which was constructed to overcome the disadvantages of (1) falling apart, (2) inaccurate angles, (3) restricted rotation without falling apart, and (4) nondistortable angles.
