What kind of decay would you expect lithium-8 to undergo, assuming it is not stable? (Lithium is the third element.)
Order the hydrogens for each molecule in the order you would expect to observe the peaks (upfield/downfield) for 3-methylbutylacetate, 3-methylbutanal, 3-methyl-1-butanol. Report the peaks as you see them for the proton NMR using the tables below: Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Look at the 13C-NMR and list the peaks and assign them to the carbons in each. What similarities did you notice with the NMR peaks in the three compounds?...
What kind of decay, and why, would you expect from each of the following? Note that if you look these up on the internet, you may find that each decays by more than one mechanism. The only correct/acceptable answers will be those that could be reasonably predicted based upon nuclear makeup. S-35 Ac-226 C-11 Ti-52 Md-257 O-15
12. In a HPLC chromatogram, peak A elutes at 2.5 min and peak B elutes at 3.0 min. The width of peak A is 0.8 min and peak B is 0.6 min. What is the resolution? Are these two peaks baseline resolved (explain your reasoning)? If not, change a specific parameter that would make these two peaks baseline resolved and calculate new resolution. Diagram both chromatograms (original question and baseline resolved) (8 pts)
Carbon-11 is radioactive. How would you expect it to decay? Like all nuclides with more than 83 protons, radon-226 is radioactive. If it decays through alpha emission, provide the identity of the nucleus that remains Pb from 228Th, which proceeds by a series of decay reations involving the step-wise Write a nuclear reaction for each step in the formation of emission of a,a,a,a,B.B
