- Choose the alkene or alkenes that would produce two 1H NMR doublets with a J = 1 to 2 Hz, and ones that would produce one unique 1H NMR signal, and ones that would produce two 1H NMR doublets with a J = 15 to 18 Hz.Why is it that nuclei closer to an OH (alcohol) group appear at higher chemical shift?Which protons are in the region from 7.0 – 8.0ppm and at 2.3ppm? please be specific for 2.3, 7.8, 7.35,7,5 and 8 ppm with singlet, doublet too
- 23. Consider the mass spectrum of 2-bromopentane, which exhibits a molecular ion peak at m/z = 150 (a) One fragment appears at M−79. Would you expect a signal at M−77 that is equal in height to the M−79 peak? Explain. Draw the structure of this fragment.With the informations below, would the nitrogen show a signal on the CNMR?a) Describe how two protons in CH2 functional group split the signal of carbon to a triplet? b) why don’t we observe carbon signal splitting by adjacent carbon(s) atoms?
- The methyl protons in acetaldehyde appear at a shift of 2.20 ppm, while the aldehydic proton appears at 9.80 ppm. In a 60 MHz NMR with an external field of 1.5 T, what is the magnetic field experienced by each type of proton? Explain why the presence of 3 protons on the adjacent carbon split the aldehydic proton peak into a quartet.Identify the expected base peak in the mass spectrum of 2,2,3-trimethylbutane.
