Question

Can you please give as much detail as posible, I am completely lost.

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 (°C) Density (g/mL) OH Isopropanol C3H80 ver 60.1 82.5 0.786 Нас CH3 O Ethyl acetate C4H802 88.11 77.1 0.902 H3C CH3 Propyl acetate CsH1002 CH3 102.13 102 0.888 H2C GLC of Isopropanol, Ethyl acetate and Propyl acetate "Ethyl acetate peak" "Isopropanol peak" "Propyl acetate peak" Intensity (UV) "Ethanol peak" 0 1 4 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.
