The mass spectrum of compound A shows molecular ion peak at m/z 88. The IR spectrum of this compound has a broad peak between 3200 and 3550 cm-1. The 1H NMR spectrum of A shows the following peaks: a triplet at d 0.9, a singlet at d 1.1, one more singlet at d 1.15, and a quartet at d 1.6. The area ratio of these peaks is 3:6:1:2. The 13C NMR contains 4 signals. In the space below, propose a...
A simulated mass spectrum of carbon is shown in Figure 1. What mass (average or isotopic) is in mass spectrometry? Explain. Queremos in Macedond should always be blind in shubtions. Now let's look at the axes in the mass spectrum... Figure 1. Mass spectrum of carbon 5. What is the y-axis? What correlation exists between peak heights in Figure 1 and the relative abundances in Table 1. The y axis in the percent abndoare. 6. What is the x-axis? Compare...
