    DAT High-Yield Organic Chemistry — C-13 NMR Symmetry Question (Dr. Romano) | DAT Destroyer | OAT Destroyer

    Question: How many distinct C-13 NMR signals does C₆₀ (buckminsterfullerene) produce? Answer: Even though C₆₀ contains 60 carbon atoms, it produces only 1 C-13 NMR signal. This is because the molecule is extraordinarily symmetrical — every carbon atom occupies an identical environment. In NMR...
