Unformatted text preview: and faster rate of evaporation, this indicates that the intermolecular forces between the bonds of ethyl acetate were not as strong as those of isopropyl alcohol. Based on the retention times given by the chromatogram of the TA, the substances could be identified because the retention times correspond to the boiling points, where the lower the boiling point, the lower the retention time. Therefore, the peaks on the chromatogram can be identified as methyl acetate, ethyl acetate, isopropyl acetate, and normal propyl acetate in that order. On the chromatogram of unknown liquid I, the three peaks would match up to methyl acetate, ethyl acetate, and normal propyl acetate based on their retention times. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Name Liz Zharovsky Bench C19 Lab day and section Tuesday - 2 TA Ramyaa Mathialagan Partner Siqi Liu Title: Gases: Evaporation, vapor pressure, and gas separation...
