TNT Detonation TNT is stable in the presence of shock, but can be detonated by adding a chemical priming agent.
A New "Bottom-Up" Framework for Teaching Chemical BondingTami Levy Nahum, Rachel Mamlok-Naaman, Avi Hofstein, and Leeor Kronik This article presents a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties. Levy Nahum, Tami; Mamlok-Naaman, Rachel; Hofstein, Avi; Kronik, Leeor. J. Chem. Educ.2008, 85, 1680.

A More Challenging Interpretative Nitration Experiment Employing Substituted Benzoic Acids and AcetanilidesEdward M. Treadwell and Tung-Yin Lin An experiment is described involving the nitration of ortho or meta, monosubstituted benzoic acids and monochlorinated acetanilides with nitric acid to evaluate the regioselectivity of addition through computational methods and 1H NMR spectroscopy. Treadwell, Edward M.; Lin, Tung-Yin. J. Chem. Educ.2008, 85, 1541.

Interactive Molecular OrbitalsWilliam F. Coleman The majority of Introductory Chemistry texts provide students with an adequate introduction to the visual aspects of the molecular orbital model for homonuclear diatomic molecules. The treatment of heteronuclear diatomic and polyatomic molecules is less uniform. Heteronuclear diatomics, when mentioned, are invariably treated as being derived from homonuclear diatomics. While the atomic orbital energy level differences in heteronuclear diatomics is sometimes pictured, the consequences of those differences for the resultant molecular orbitals are rarely discussed. The discussion of polyatomic molecular orbitals in these texts is limited to showing that parallel p-orbitals produce delocalized pi molecular orbitals. The molecules typically mentioned in this context are benzene, nitrate ion and carbonate ion. However, It is rarely pointed out that the six p-orbitals in benzene would form 6 pi molecular orbitals, and that only one of these orbitals would look like the picture in the text.These interactive modules are designed to clarify this subject.
