Figure Number: 15-05-40P30 Title: End-of-Chapter Problem 30 Caption: Proton NMR spectrum associated with end-of-chapter Problem 30. Notes: The proton NMR spectrum shown results from obtaining the spectrum of the product of the reaction of benzene with a Friedel-Crafts acylation reagent followed by Clemmensen reduction of the acylation product. Determine the identity of the acyl chloride used in the Friedel-Crafts acylation reaction.
