    I wish when you go to school the Professors would teach you this way; many times you wish you didn't go to class because you come out confused all the more. Thank you for such a wonderful explanation.

    If everyone just taught like this (not leaving little details like the equation for m/z) no one would have to worry about bad teachers!

    Thanks for the video. I am a little confused here. I think since we get more of a primary carbo cation than a secondary carbo cation, shouldn't the graph on the left side indicate that it is a primary carbo cation?

    Why is the 43g/mole peak approximately the same for pentane and 2-methylbutane? If you drop a CH2CH3 off of 2 methylbutane, the resulting charge is on a secondary carbon. If you drop a CH3CH2 off of pentane you get the resulting charge on a primary carbon. Am I missing something here?

  • @fipacunha
    @fipacunha 6 ปีที่แล้ว +1

    In the last exercise, the peak at 27 is a secondary fragment ? Which means that the etil cation suffers another fragmentation loosing one hyrogen and resulting a fragment of 27 ? And in pentane, why is the 43 fragment the most abundant ? Pentane only gives primary carbocation ? Is this related to the number of carbons in the fragment generated justifying that the peak at 43 is greater than at 57 ?

    39 (189 ), 41 (134 ), 26 (91 ), 15 (72 ), 42 (60 )

  • @291ayl
    @291ayl 2 ปีที่แล้ว

    Quick question,if you broke a hydrogen carbon bond and the hydrogen took both electrons becoming a hydride ion why wouldn't that be detected? Just because its an anion instead of a cation?

  • @kreynolds1123
    @kreynolds1123 5 ปีที่แล้ว

    Question, Say your looking for relative isotopic difference between hydrogen and deuterium. Starting with a molecule it could be HH DH or DD. An electron gun could seperate a DH into D and H how can we identify the difference between HH and D? Or does then detector need to be sensitive enough to identify electron mass?
