Molecular Models of Polymers Used in Sports EquipmentWilliam F. Coleman The Featured Molecules this month are a number of monomers and their associated polymers used in making equipment for a variety of high-impact sports. The molecules provide students with an introduction to an important area of applied chemistry and also enable them to examine complex structures using the models they have seen applied to small molecules. Coleman, William F. J. Chem. Educ.2008, 85, 1456.
Sulfur dichloride, SCl2William F. Coleman, Randall J. Wildman This month's molecule is sulfur dichloride, SCl2. This and other small inorganic molecules are discussed in the article by Matta and Gillespie. They describe electron density in molecules and how to analyze it to obtain information about molecular bonding and structure. Different depictions of electron density in SCl2 and other small molecules emphasize different aspects of their electron density and of the structures of the molecules.

Penicillin and Vitamin B12William F. Coleman The WebWare Molecules for July are mentioned in the article "The History of Molecular Structure Determination Viewed through the Nobel Prizes", by Jensen, Palenik, and Suh. One of the recipients discussed, Dorothy Crowfoot Hodgkin, won the Nobel Prize in Chemistry in part for determining the structures of penicillin and vitamin B12.

Amylose and PolystyreneWilliam F. Coleman The WebWare molecules of the month are amylose and polystyrene, which are examined in JCE Classroom Activity #57: "Pondering Packing Peanuts Polymers". In the activity, students investigate polymers and their chemical composition. The structures below show several repeating units of the two polymers. The helical, 50-unit amylose shows the structure that complexes with iodine to produce the blue charge-transfer complex in the starch iodine test.
