Question:
When the 1H NMR spectrum of acetone, CH3COCH3, is recorded on an instrument operating at 200 MHz, a single sharp resonance at 2.1 δ is seen.
(a) How many Hz downfield from TMS does the acetone resonance correspond to?
(b) If the 1H NMR spectrum of acetone were recorded at 500 MHz, what would the position of the absorption be in δ units?
(c) How many Hz downfield from TMS does this 500MHz resonance correspond to?
