Chemical & Physical Change  American Chemical Society
Everything you see and touch has the ability to change. Sometimes substances change to form new substances. This is called a chemical change. Other times substances change but keep the same identity. This is called a physical change. Try these activities to learn more about chemical and physical change.

Molecular Model of Zincon  William F. Coleman
The Featured Molecules this month are the tautomeric forms of the colorimetric reagent zincon, used in the paper by Maria Mar Areco, Maria dos Santos Afonso, and Erika Valdman on the bioabsorption of zinc, and by extension other metal ions, by seaweed. The structures presented have been calculated at the DFT/6-31G(d) level using the B3LYP functional. These structures represent energy minima, but not necessarily global minima. The structures could be used as an introduction to the concept of tautomerism, with students being asked to develop a definition of the term based on their observations of the difference(s) in linkage in the two forms. An intramolecular hydrogen bond is found in each structure, and introductory chemistry students could be encouraged to look for these structural features in molecules that are more complex than those typically encountered to introduce hydrogen bonding. More advanced students could use computational techniques to explore the energy differences between the two forms, and compare those differences to the ones observed between more traditional keto/enol examples.

Sunscreens  William F. Coleman
Reinforcing the "Heath and Wellness" theme of National Chemistry Week 2004, the featured molecules for this month are all found in commercial sunscreens, or in the synthesis of sunscreen materials. The paper by Stabile and Dicks introduces students of organic chemistry to the synthesis of cinnamate esters used in sunscreen products. Several of the papers referenced by those authors, most notably a paper by Doris Kimbrough (J. Chem. Educ. 1997, 74, 51?53), present the structures of additional sunscreen components. Although the details of the synthesis are beyond the scope of most introductory courses, these molecules present an excellent opportunity for introducing students to the absorption of radiation that is far more relevant to their lives than the line spectra of hydrogen and other atoms. Such a discussion could be extended to include more delocalized dyes such as those frequently studied in physical chemistry courses as a test of particle-in-a-box models, and students could be asked about those molecules as sunscreens, which raises an interesting intersection between aesthetics and spectroscopy.

Introduction of Aquatic Chemistry in General Chemistry Curriculum;Spreadsheet Calculation Approaches  Chulsung Kim
Fundamental aquatic chemistry concepts may be introduced in general chemistry classes by computing ionization fractions and buffer intensity of aqueous phase carbonate systems. This Excel spreadsheet may used to build graphic presentations of a titration curve, distribution diagram, and buffer intensity as a function of pH. Accompanying activities are designed to enhance the concepts of acid-base equilibrium through exploring the relationship between pKa/pKb, pH of the solution, ionization fractions, and buffer intensity, and to exercise students graphing skills.

Molecular Models of Candy Components  William F. Coleman
This month's Featured Molecules come from the paper "A Spoonful of C12H22O11 Makes the Chemistry Go Down: Candy Motivations in the High School Chemistry Classroom" by Fanny K Ennever on using candy to illustrate various principles. They include sucrose and the invert sugar that results from the hydrolysis of sucrose. Students should look for structural similarities between sucrose and the hydrolysis products glucose and fructose, and verify that all three are indeed hydrates of carbon. They should also inspect the models to see whether the position of the substituents in the five and six membered rings are the same in the sucrose and in the hydrolysis products. Also included are two esters important in fruit flavoring of candies. Flavor and aroma are inexorably intertwined in the taste experience and no single compound is responsible for that experience. Methyl cinnamate, included here, is one of over 100 esters, and over 300 compounds, involved in the taste of strawberries (1). Isoamyl acetate is a major component of the taste of bananas. Lastly, chocolate, perhaps nothing else need be said. There is a great deal of confusion in the popular press and on the internet between theobromine, found in cocoa beans, and caffeine. Both molecules are included here and students should easily see why the two might be confused. Consequently there are many exaggerated claims about caffeine in chocolate. An interesting assignment would be for teams of students to find reliable data on the physiological effects of these similar molecules, and to find good analyses on the actual level of caffeine in cocoa beans, versus the amount added in the candy production process, if any.
