Acid-Catalyzed Enolization of β-Tetralone  Brahmadeo Dewprashad, Anthony Nesturi, and Joel Urena
This experiment allows students to use 1H NMR to compare the rates of substitution of benzylic and non-benzylic a hydrogens of -tetralone and correlate their findings with predictions made by resonance theory.
