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!!! Step...
