Question

Which of the following statements about NMR spectroscopy is correct and most complete ? (Hint: Be careful.) (A) 1C NMR spectroscopy is the second most common NMR spectroscopy in organic chemistry after H NMR (B) cyclohexane has two signals in its NMR spectrum at room temperature, one corresponding to its axial hydrogens and one to its equatorial hydrogens (C) the NMR spectra of (R,R)-trans-1,2-dimethylcyclohexane and (S,S)-trans-1,2-dimethylcyclohexane will be identical in CDCl3 (D) all of the above statements are true

Explanation / Answer

Ans : C (R,R)-trans-1,2-dimethylcyclohexane and (S,S)-trans-1,2-dimethylcyclohexane are enantiomers. Enantiomers are having same NMR).
