On Capillary Rise and Nucleation R. Prasad A comparison of capillary rise and nucleation shows that both phenomena result from a balance between two competing energy factors: a volume energy and a surface energy. This comparison may help to introduce nucleation with capillary rise, a topic familiar to students. Prasad, R. J. Chem. Educ. 2008, 85, 1389.

Organic Spectroscopy Laboratory: Utilizing IR and NMR in the Identification of an Unknown Substance Neil M. Glagovich and Timothy D. Shine An undergraduate organic laboratory designed to teach the use of IR and NMR spectra interpretation in the identification of an unknown substance has been developed. This laboratory requires the student to obtain the IR spectrum of an unknown substance and, from the interpretation of that spectrum, determine which of several possible functional groups is present in the molecule. Using this information and either the melting point or boiling point of the unknown, the student is able to determine a list of likely candidates (usually between eight and twelve suspects collated from a supplied table of possible compounds). The student will then draw the structures for all candidate compounds and, from those structures, predict the 1H- and 13C-NMR spectra for each. Glagovich, Neil M.; Shine, Timothy D. J. Chem.

Rotational Mobility in a Crystal Studied by Dielectric Relaxation Spectroscopy. An Experiment for the Physical Chemistry Laboratory Madalena S. C. Dionísio, Hermínio P. Diogo, J. P. S. Farinha, and Joaquim J. Moura-Ramos In this article we present a laboratory experiment for an undergraduate physical chemistry course. The purpose of this experiment is the study of molecular mobility in a crystal using the technique of dielectric relaxation spectroscopy. The experiment illustrates important physical chemistry concepts. The background of the experimental technique deals with the concepts of orientational and induced polarization and frequency-dependent relative permittivity (or dielectric constant). The kinetic concepts of temperature-dependent relaxation time, activation energy, and activation entropy are involved in the concept of molecular mobility. Dionísio, Madalena S.

The Pythagorean Theorem and the Solid State Brenda S. Kelly and Allen G. Splittgerber Solid-state parameters such as radius ratios, packing efficiencies, and crystal densities may be calculated for various crystal structures from basic Euclidean geometry relating to the Pythagorean theorem of right triangles. Because simpler cases are often discussed in the standard inorganic chemistry texts, this article only presents calculations for closest-packed A-type lattices (one type of particle) and several compound AB lattices (A and B particles) including sodium chloride, cesium chloride, zinc blende (sphalerite), wurtzite, and fluorite.

Self-Assembled Colloidal Crystals: Visualizing Atomic Crystal Chemistry Using Microscopic Analogues of Inorganic Solids Neal M. Abrams and Raymond E. Schaak Monodisperse spherical colloids spontaneously crystallize into close-packed crystals, in analogy to the simple crystal structures of many of the elements. Since colloids are orders of magnitude larger than atoms, students can directly observe crystal structure and behavior in a microscope using colloidal crystals. This laboratory exercise provides a modular series of materials science experiments appropriate for undergraduate chemistry and engineering majors. The individual modules include aspects of chemical synthesis (monodisperse SiO2 and polymer spheres), self-assembly (colloidal crystallization), and structural characterization through microscopy (optical and scanning electron microscopies) and optical spectroscopy (optical diffraction and UVvisible spectroscopy).

A simple, visually-compelling demonstration shows students how stirring or pouring can segregate a mixture and create a nonuniform sample. The demonstration uses colored beads and other inexpensive, readily-available materials. The demonstration has proven useful for illustrating the importance of sample handling for students studying analytical chemistry and environmental chemistry. Fritz, Mark D. J. Chem.

Solvent-Free Synthesis of Chalcones Daniel R. Palleros The solvent-free synthesis of 20 chalcones was carried out by grinding the benzaldehyde (unsubstituted, 4-methyl, 4-methoxy, 3-chloro, or 4-chloro) and the acetophenone (unsubstituted, 4-methyl, 4-bromo, or 4-methoxy) in the presence of solid sodium hydroxide with a mortar and pestle. In general, the chalcones were obtained in high yields and high purity. Minor quantities of ketol and Michael addition product were detected by NMR spectroscopy. These side-products were easily removed by recrystallization. Palleros, Daniel R. J. Chem. Educ. 2004, 81, 1345.

Melting Point and Molecular Symmetry R. J. C. Brown and R. F. C. Brown In 1882 Thomas Carnelley observed that high molecular symmetry is associated with high melting point. The application of the rule to a number of different molecular crystals is discussed. The rule applies to different categories of crystal for different reasons, which can be explained by thermodynamic analysis. Brown, R. J. C.; Brown, R. F. C. J. Chem. Educ. 2000, 77, 724.

Covalent and Ionic Molecules: Why Are BeF2 and AlF3 High Melting Point Solids whereas BF3 and SiF4 Are Gases? Ronald J. Gillespie Calculated ionic charges show that BF3 and SiF4 are predominately ionic molecules yet in contrast to BeF2 and AlF3 they exist as gases at room temperature and form molecular solids rather than infinite three-dimensional "ionic" solids at low temperature. Whether or not ionic molecules form a three-dimensional infinite ionic lattice or a molecular solid depends more on relative atomic (ionic) sizes than on the nature of the bonding in the isolated molecule.
