Please show all work and explanations if possible.
Thank you so much!
4. (4pts) A mass spectrum shows significant peaks at m/z 87, 115, and 143. Which of the following compounds is responsible for that mass spectrum: 4,7-dimethyl-1-octanol, 2,6-dimethyl-4-octanol, or 2,2,4-trimethyl-4-heptanol? Provide structures of the cationic fragments that support your choice and provide the mechanism for the formation of ONE of these fragments from the molecular ion. он он но

1) Predict and assign in the major peaks in the IR spectrum of a) n-propyl acetate, CH3COOCH2CH2CH3 and b) 2-methyl-1-propyl acetate, CH3COOCH2CH(CH3)2 2) Predict and assign in the major peaks in the 1H NMR spectrum of a) n-propyl acetate, CH3COOCH2CH2CH3 and b) 2-methyl-1-propyl acetate, CH3COOCH2CH(CH3)2 3) Predict the appearance of the 1H NMR spectrum of a) methyl acetate, CH3COOCH3 and b) ethyl propionate, CH3CH2COOCH2CH3 Thank you!
. Here is the NMR of the ethyl acetate. We combined all the
fractions that the class distilled when doing Experiment 2 into one
sample and took the NMR of that one sample. a. Assign all the peaks
to the protons in ethyl acetate b. Based on this spectrum would you
say they sample is pure? Why or why not?

In the stretching region of the spectrum, identify as many IR peaks as possible that are consistent with the molecular formula. List the wavenumber of each identifiable peak and the type of bond or structural grouping to which it corresponds. Draw the structures of all possible molecules that are consistent with both the molecular formula and the stretching frequencies present in the IR spectrum. On the basis of all frequencies, both stretching and bending, ) state which structure(s) can be...
Explain how the peaks in NMR spectrum correspond to the
structure of isopentyl acetate.
