Abstract
The concept of gas chromatography–mass spectroscopy (GC–MS) has been successfully incorporated into our general chemistry curriculum at City College of San Francisco. In particular, students are asked to separate and analyze a mixture of the group 6 transition-metal carbonyl compounds, Cr(CO)6, Mo(CO)6, and W(CO)6. From the mass spectral data, our students are able to determine the atomic mass of the transition metal. In addition, utilizing Mo(CO)6 as an internal standard, our students are able to quantify the quantity of Cr(CO)6 and W(CO)6 in an unknown mixture.
