When the following compound is treated with a strong Brnsted acid, a stable carbocation
Chapter 15, Problem 15.85(choose chapter or problem)
When the following compound is treated with a strong Brnsted acid, a stable carbocation A is formed. (a) Propose a structure for carbocation A, and draw its resonance structures. (b) The proton NMR spectrum of carbocation A at 210 C consists of four singlets at d 1.54, d 2.36, d 2.63, and d 2.82 (relative integral 2 : 2 : 2 : 1). Explain why the structure of A is consistent with this spectrum by assigning each resonance. (c) Explain why the NMR spectrum of A becomes a single broad line when the temperature is raised to 113 C. (Hint: See Sec. 13.8.)
