Where does the m+ peak come from in mass spec? I understand it is mass of compound, but what is being ionized to lead to formation of the ion without breaking into fragments? Mechanism would be appreciated.

The molecular weight of a compound is typically indicated by the heaviest peak on a mass spectrum, which i presumed to correspond to the molecular ion (M*). For smaller compounds, the heaviest peak tends to also be the most intense peak. The lighter peaks in the spectrum result from fragmentation of the molecule into smaller ions. Since peak intensity correlates to the relative stability of the ions produced, the peaks of the ionized fragments can be more intense than the...

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!!!

I am studying Acids & Bases. I understand that Acids ionize, creating ions that were not previously there. I understand that Bases dissociate, simply breaking the compound apart into its individual ions. Acids ionize to create (H3O) ions by producing/donating an (H+) ion Bases dissociate, with one ion being (OH-) But I am confused about the Bases.... I get that the compound breaks apart, and that bases dissolve/accept protons but if you are looking at this chemical equation, which dissociates...

Please help identify the
organic compound using mass spec, ir spec, CNMR, and HNMR.
From looking at the mass spec, I believe the molar mass of the
uknown organic compound to be 122 g/mol
From looking at CNMR, I believe there are at least 5 carbons for
each of the 5 peaks. I recall from class that there can be more due
to symmetry, but am not certain how to tell.
Above are all of the graphs given to me...

The low-resolution mass spectrum of an unknown monosubstituted benzene showed a molecular ion (M+) peak at m/z 150. Combustion analysis of a sample of this compound indicated that the compound contained C, H, and O only and had an empirical formula of C3H1002. The IR spectrum of the unknown compound is shown below. The 'H NMR spectrum of the unknown compound did not show a peak in the 9.10 ppm range. D 4000 9000 2000 1500 1000 RAVENUGERII What is...
