Benzene underwent a Friedel-Crafts acylation reaction followed by a Clemmensen reduction. The product gave the 1H NMR spectrum shown above. What acyl chloride was used in the Friedel-Crafts acylation reaction? Hint: It would be helpful if you first assign a structure to the compound shown in the 1H NMR spectrum.
Can someone help explain how to tell exactly which acyl chloride was used?
NMR spectrum is attached. Thank you.
Aromatic ring is considered but there must be some more information given with it.
