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!!!
