What is the relationship between the three products obtained when we replace H  _a, H_b, and H_c of methylcyclohexane with deuterium? How many signals would you expect the three hydrogens to produce in the ¹H NMR spectrum?

• A. The products are enantiomers and the three hydrogens will produce one signal in the ¹H NMR spectrum.
• B. The products are the same compound and the three hydrogens will produce one signal in the ¹H NMR spectrum.
• C. The products are diastereomers and the three hydrogens will produce three signals in the ¹H NMR spectrum.
• D. The products are enantiomers and the three hydrogens will produce three signals in the ¹H NMR spectrum.

Answer: (B)
