We're being asked to determine the number of 1H–NMR signals present in the given molecule.
Recall that the number of 1H–NMR signals depend on the number of unique, non-equivalent protons in the molecule.
Equivalent protons have the same prospective on the molecule, and are located on the same carbon.
Symmetry reduces the number of signals.
How many unique 1H-NMR signals exist in the spectrum of the following compound?
