- For each problem, you must: 1) Calculate the degree of unsaturation. -1 2) Assign the principal IR absorption bands above 1500 cm 3) Draw the structure of the compound 4) Label the protons on your structure with letters and assign them to peaks on the NMR spectrum (see the example below). 4.0 C 2H 3.5 3.0 2.5 D 1H 3.0 This peak is a magnified version of this peak A 2.8 2.0 1H B zum 2.6 B 2H Each problem contains the formula of the compound, the IR spectrum (with axes in cm³¹ vs. % transmission), and the ¹H NMR spectrum (with axis in PPM shift). Some NMR spectra show a peak hovering above the baseline. This is a magnified view of one of the actual peaks, to allow you to see splitting more clearly. 1.5 2.4 OHD A 3H 1.0 PPM 0.5Chart 1 ▾ ⠀ H G fr Axis Title F E D 1/T -1.20397 0.003356 -0.59784 0.003145 -0.16252 0.003003 0.262364 0.002874 LN K Chart Title 0.4 0.2 0 0.0034 0.0033 0.0032 0.0031 003 0.0029 0.00282 -0.4 -0.6 -0.8 -1 -1.2 -1.4 TK Axis Title C y=-3033.1x+8.9597 R² = 0.999 298 318 333 348 K -Series1 Linear (Series1) C O B 0.3 0.55 0.85 1.3 + 2 T A > FNM 45 1 25 2 3 60 4 75 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Consider the following data to determine the molar entropy AS°: Temp (°C) Keq 0.3 0.55 0.85 1.3 25 45 60 75 a. 364.82 J/K.mol b. 74.49 J/K.mol c. 86.37 J/K.mol d. 89.59 J/K.mol e. 64.25 J/K.mol Clear my choice351145 TECHNO Define fundamental unit with an example.
