IR spectroscopy can be used to determine if you successfully separated the contaminant and 2-phenethylamine mixture. What peaks would indicate that 2-phenethylamine was still present? Select one:
a. Two strong, sharp peaks at 3050 and 1750 cm ¹. b. Two strong, sharp peaks ~3300 cm ¹.
c. Strong, sharp peaks at 2950, 1750, and 1200 cm ¹.
d. Strong, sharp peaks at 3050, 1600, and 1500 cm ¹.
f. A broad peak from 2800-3200 cm-1. O f. Sharp, strong peaks at 3400 and 1200 cm-¹.
