Classify each of the following statements as true or false True A proton signal

Question

Classify each of the following statements as true or false True A proton signal in the NMR will be split into three peaks if it has two neighboring protons. Two proton resonances that are coupled to one another will each be split with different coupling constants Infrared spectroscopy can give us information about functional groups. Molecules will fragment in the mass spectrometer to give only the most stable fragment. The infrared absorbance of a ketone carbonyl will appear at 2200 cm^-1. The energy required to flip a nuclear spin state aligned with a magnetic field lies in the microwave region of the electromagnetic spectrum.
