Can you help me sort this out?
E Recall, split is how a signal appears in the NMR. The split is determined by N+1, where N is the number of hydrogen NEXT to the signal hydrogen. For example, carbon A is a CH3, it is next to carbon B which is a CH2. So the signal for carbon A will be a triplet (N+1; 2 + 1 = 3, a triplet). The integration is what the signal consists of and...

In Mass Spectrometry (MS) the molar mass of compounds can be determined. The so-called "molecular ion" corresponds to the molecular mass when Electron Impact Mass Spectrometry (EIMS, one of several common MS techniques) is used. It is important to realize, though, that the mass detected by MS depends on the isotopes present in the molecule. The questions below try illustrate the impact of isotope distribution in a molecule. What is the molar mass of the compound shown below? What is...
