This is for my mass spectrometry lab report.
I have to figure out the m/z of the base peak and in order to
do so I need to know where the weakest bond is for each compound so
I can split them up.
Please do that for me for each of the compound. I just want to
double check my work.
I’ve attached on the second picture an example of one of the
compound.
Thank you ahead of time!!!

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...

You will use a relatively new type of mass spectrometry, ASAP-MS, to verify the molecular weights of your isolated compounds from part 1. You will also carry out melting point determinations of the obtained solids from part 1 both as a way to confirm their identities and to assess their purity. Part 1 was an acid/base extraction with the original mixture being a 1:1:1 mixture of trans-cinnamic acid, ethyl 4-aminobenzoate (benzocaine), and N,N-diethyl-3-toluamide (DEET). Write a prediction of the number...

On your internship, you visit the Mass Spectrometry Lab. Mass spectrometry can identify short peptide fragments based on their molecular weights. Your fellow intern Jerry has neglected to label his tubes of amyloid beta peptide 42 after digesting them with some proteases that we learned about in Module 6: pepsin, trypsin, and chymotrypsin. Help him figure out what protease is in each tube. Jerry’s supervisor has the fragments listed in the same order as the original peptide primary sequence, which...
