Which one of the following statements is not true? If the two protons in a CH2 group are diastereotopic, they will couple with each other. O Helium-4 is a magnetically inactive nucleus. O If you cool cyclohexane to a low enough temperature, you can distinguish between the axial and equatorial protons in NMR spectroscopy. The magnet in a 400 MHz NMR spectrometer is stronger than the magnet in a 500 MHz spectrometer. You would observe carbon-carbon coupling in the 13C NMR spectrum of propane if each of the carbon atoms were carbon- 13.

Construct a simulated proton-decoupled ¹³C NMR spectrum for tert-butylamine. Drag the resonance signal to the appropriate chemical shift positions. Then label the box above each signal with the expected splitting if there were no proton decoupling. The splitting abbreviations are s = singlet, d = doublet, t = triplet and q = quartet.

For the dimedone molecule, how many different signals would you see in the proton NMR? Assume you can see them all
A student needs to prepare a ¹H NMR sample for an organic compound soluble in chloroform (CHCI3). The student cannot use CHCI 3 as the solvent for the sample, but rather uses deuterated chloroform (CDC13) because: O CDC13 is more polar. O CDC13 will not produce a signal in the ¹H NMR spectrum, and therefore will not mask the signals of the compound. O The compound will be more soluble in CDCI 3. O CDC13 is cheaper than CHCI 3.
