Vapor Pressure: Molecular Size The vapor pressures of pentane, hexane, and heptane are compared. The vapor pressures of methanol and ethanol are compared. Molecular models of the compounds are shown.
Study of Molecular-Shape Selectivity of Zeolites by Gas ChromatographyPei-Yu Chao, Yao-Yuan Chuang, Grace Hsiuying Ho, Shiow-Huey Chuang, Tseng-Chang Tsai, Chi-Young Lee, Shang-Tien Tsai, and Jun-Fu Huang This analytical or physical chemistry sorption experiment uses hexane isomers as probe molecules to demonstrate the "molecular-shape selectivity" behavior of zeolites. Students can also modify the sorption protocol to build their own experiments. Chao, Pei-Yu; Chuang, Yao-Yuan; Ho, Grace Hsiuying; Chuang, Shiow-Huey; Tsai, Tseng-Chang; Lee, Chi-Young; Tsai, Shang-Tien; Huang, Jun-Fu. J. Chem. Educ.2008, 85, 1558.

The Aromaticity of Pericyclic Reaction Transition StatesHenry S. Rzepa Presents an approach that combines two fundamental concepts in organic chemistry, chirality and aromaticity, into a simple rule for stating selection rules for pericyclic reactions in terms of achiral Hckel-aromatic and chiral Mbius-aromatic transition states. Rzepa, Henry S. J. Chem. Educ.2007, 84, 1535.

Hexane 1 (GCMP)David M. Whisnant Hexane 1: this is a resource in the collection "General Chemistry Multimedia Problems". Hexane, a liquid hydrocarbon with the formula C6H14, burns when ignited in the presence of oxygen. In this problem we will observe videos of this combustion reaction. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
