Reactions: Acetylene Preparation of acetylene and the reaction of chlorine with acetylene are demonstrated. An antique carbide lamp is also demonstrated.
Hydration of Acetylene: A 125th AnniversaryDmitry A. Ponomarev and Sergey M. Shevchenko The discovery the hydration of alkynes catalyzed by mercury ions by Mikhail Kucherov made possible industrial production of acetaldehyde from acetylene and had a profound effect on the development of industrial chemistry in the 1920th centuries. Ponomarev, Dmitry A.; Shevchenko, Sergey M. J. Chem. Educ.2007, 84, 1725.

Ozonolysis Problems That Promote Student ReasoningRay A. Gross Jr. The structural features inherent in acyclic monoterpenes that follow the isoprene rule often lead to unique sets of ozonolysis products from which their structures, excluding stereochemistry, can be determined from molecular formulas only. This article shows how students may elucidate the structures of these compounds by analysis of the oxidative and reductive workup products. Gross, Ray A., Jr. J. Chem. Educ.2006, 83, 604.

Synthesis of Unsymmetrical Alkynes via the Alkylation of Sodium Acetylides. An Introduction to Synthetic Design for Organic Chemistry StudentsJennifer N. Shepherd and Jason R. Stenzel Teams of students design a microscale synthesis of an unsymmetrical alkyne using commercially available terminal alkynes and alkyl halides and characterize the resulting products using TLC, IR, and 1H NMR spectroscopy. Depending on the chosen reactants, students observe both substitution and elimination products, or in some cases, no reaction at all. Shepherd, Jennifer N.; Stenzel, Jason R. J. Chem. Educ.2006, 83, 425.
