Study of Molecular-Shape Selectivity of Zeolites by Gas Chromatography Pei-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.

On the boiling points of the alkyl halides Correla, John Most textbooks spend some time discussing the relationship between boiling point and molecular structure, however, their reasons behind this relationship differ. This variation among textbooks warrants further investigation and discussion in order to uncover which of the factors are the major contributors to the variation of boiling point. Correla, John J. Chem. Educ. 1988, 65, 62.
