How could you use IR spectroscopy to determine if the following reaction was successful? OH DMP O Look for the appearance of a signal at 3200-3600 cm 1 and the disappearance of a signal at 3050 cm ¹. O Look for the appearance of a signal at 3050 cm ¹ and the disappearance of a signal at 1720 cm-1. O Look for the appearance of a signal at 3200-3600 cm¹ and the disappearance of a signal at 1720 cm ¹. O Look for the appearance of a signal at 1720 cm1 and the disappearance of a signal at 3200-3600 cm ¹.

3. Given the following molecule, please (1) draw what you might predict its standard spectrum and DEPT 90 and DEPT 135 spectra would look like, and (2) based on that picture, assign each of the numbered carbons on the original structure to a peak in the standard 13C spectrum. I 1 2 6 4 Br 2 3 7 Br 5 Standard 13C 220 200 180 160 140 120 100 80 60 40 20 0 DEPT 90 220 200 180 160 140 120 100 80 60 40 20 DEPT 135 220 200 180 160 140 120 100 80 60 40 20 0

Lable the peaks of diphenylmethanol (product of benzophenone) and explain why each peak is the way it is Thank you
