Immediate help needed
Starting with benzene and any other reagents, show by a series of reactions how you could prepare the following compounds: Circle the beat answer: In ^1 H-NMR spectroscopy. a) irradiation of the sample with radio waves causes the nuclei of hydrogen atoms to undergo a "spin flip" in the presence of an externally-applied magnetic field. b) the sample is irradiated with infrared light and the absorption pattern is recorded. c) absorption of energy by the sample caused bonds in the molecules to undergo stretching and bending vibrational motions. d) absorption of energy by the sample causes an electron to be promoted to a higher energy molecular orbital.
