So just to be clear, in the last part of the ethyl example, it is possible to cleave off either methyl group (on the right side or the left side) to produce the 101 g/mol peak. It just wouldnt be a very big peak, even though two possibilities were contributing to it.

Hi ! I think at 16:20 there is a mistake : CH3-CHBr-CH3 because it cant be a CH2 at the end I think. And also at 16:35 : I have 122 g/mole and 124 g/mole It's only for helping you :) and thanks for you job it's realy great ! :D

At 14:08, isn't that ethyl daughter molecule technically an anion? Can a detector be introduced to detect this? Shouldn't it be curved in the opposite direction of the cations of interest, or is it truly neutral and flows straight to the exhaust in the MS?

Very helpful video! as tomorrow is my test. So much clarity in the visual representation. 👍I have a couple of doubts 1. Why the electron beam remove electron from the hetroatom atom such as oxygen, halogen and not carbon? 2. Why methyl radical peak was generated when alpha cleavage was done from right hand side?? Looking forward to the answers.

@himakshisaikia2323 4 жыл бұрын

Akeeda Sharma well I think that the electrons on heteroatoms such as oxygen, nitrogen are loosely held as these have lone pairs of electrons (non bonding electrons)...similarly for halogens.

Is the electron beam always going to knock out an electron from the lone pair? Because on a question that said "draw all the possible cationic fragments of the following molecule" my professor drew also the possibility of knocking out on electron from a bond.. I was really confused because I always thought it was the atom with lone pairs that gives up one electron.

@Knowbee 6 жыл бұрын

Good question. The beam can also knock out bonding electrons. I have videos about this. Go to my channel and watch all the fragmentation vids and you will see.

Sorry for nitpicking- species is singular and plural - that’s why we don’t talk about the human specie, it’s the human species, even though it’s only one.
