Question

Could you describe the differences of the chemical structures and solubility as well as boiling points and why each one came out sooner than the next? Thank you

Problem 3. Explaining a GLC Elution Order (6p). Below is a table of physical data for isopropanol, ethyl acetate and propyl acetate. Problem 3 Physical Constants Table Chemical Name Chemical Formula Chemical Structure Molar Mass (g/mol) Boiling Point (*) Density (g/ml) OH Isopropanol CH 0 60.1 82.5 0.786 H3C CHE Ethyl acetate CH,02 он, 88.11 77.1 0.902 H2C Propyl acetate CsH1002 Hoon CH, 102.13 102 0.888 GLC of Isopropanol, Ethyl acetate and Propyl acetate "Ethyl acetate peak "Isopropanol peak "Propyl acetate peak Intensity (uv) "Ethanol peak 0 1 2 3 Time (minutes) Assume the GLC chromatogram above is from a mixture of equal parts of isopropanol, ethyl acetate and propyl acetate. The peaks corresponding to isopropanol, ethyl acetate and propyl acetate are labeled (as well as the ethanol rinse trace peak). Explain the elution order of the three compounds (isopropanol, ethyl acetate and propyl acetate) - that is, the order of the peaks in the chromatogram. Remember, the peak closest to t = 0 is the compound first to exit (elute) from the GLC column, while the last peak corresponds to the compound that eluted last. Clearly explain the elution order on a chemical level using the physical data and structures. Your response must demonstrate a degree of understanding and depth to receive credit.
