Chemistry 241 Win/Spr 2020 LAB 2: DISTILLATION, GAS CHROMATOGRAPHY, AND NMR SPECTROSCOPY Name: __________________________________________ Section:_______ Order of report pages: 1-3: worksheet pages 4: distillation curve 5-9: NMR spectra in the order: original; 1st mL simple; 1st mL fractional; last mL simple; last mL fractional 10-14: GC printouts in the order: original; 1st mL simple; 1st mL fractional; last mL simple; last mL fractional 15-19: notebook pages Note: since you are collecting data with a lab partner, for this specific experiment, you can each annotate the GC/NMR spectra from your individual distillation, then share those spectra with your partner. If you do this, you MUST write on each spectrum who performed the analysis, Unknown # ________ 1. (4 pts) Identification of A: ______________________ Identification of B: __________________ 2. (2 pts) Distillation curve analysis. Your graph should include the curve for both the simple and fractional distillation on a single set of axes. On your distillation curve, calculate the following: A) The identities of each compound based on their boiling points B) The % composition of the original mixture based on where the curve is steepest 3. (3 pts) NMR analysis. On each
