What do you get when you blow molecules up? Watch this video to find out. Also find out how fragmentation of molecules can be used to identify a substance and why you have to be POSITIVE about RADICALS.
2 hours more for my exam and this is the best place to revise.. all explained in a very smooth manner. Keep uo your good work. You really are life saver. Thank you soo much for this wonderful service. May God bless you always. Thanks alot!
Is this the reason why a positive ion and radical always has to form? When you have fragmentation in mass spectrometry one electron that was participating in the chemical bond essentially is "lost" - what this means is that we only have one available electron to assign to two fragments - the fragment that receives the electron becomes a radical (as its charge remains balanced but it still contains an unpaired electron) but the other fragment receives no electron and now has a positive charge - so it's very key in that the electron is knocked off because this is what allows for the formation of the radicals and ions. Why does it have to be positive ions passing through the mass spectrometer? I know that it uses magnetic fields to deflect charged particles, is it just the case that the detector is synchronized to measure deflection of positive charges? Or is it the case that the ionization process is more favorable to form positively charged particles, so we create the apparatus that is built to detect deflection of positive charges? Lastly, it's the case that fragmentation is a by-product of electron impact right and not necessarily that we want to fragment the particle, but in order to positively charge these particles fragmentation occurs just so happens to occur right? But in any case it's a happy by-product because we can get additional information about mass/charge ratios of particle fragments which could be useful say for example by giving us further evidence that a proposed compound is the one present in our sample we are analyzing. Is all these things correct or are there inconsistences in my comment here? Awesome video tho. I love it and it really helped me get a more conceptual understanding of mass spectrometry which is just awesome.
