How could someone tell apart positions A and B in the proton NMR
spectrum of the molecule? There may be more than once correct
answer.
1) Chemical Shift 2) Splitting 3) Integration
Using just one answer from above, explain how A and B would
appear different (describe the appearance of both signals and how
they differ)
