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.
@@Whitelivesmatter148ate What a nice way of showing your ethnocentric views here...Have you ever considered that maybe this guy isn't from the US? Because you can't possibly assume that only Americans are being taught this subject in English...
Thank you so much for going in depth and leaving no stone unturned in your teaching. 5 minutes in and i could tell i was really gonna learn from this video! 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!
This was so clear with respect to the detection aspect , none of the other videos could solve my doubts about detection .glad to having watched this one. Respect from India
I am in love with this voice and accent. I just paused the video to comment this cuz this couldn't wait. Not to mention the explanation is excellent. Subscribed! ^_^
thank youuuu. So glad i found your channel,, I was floating in my online class today morning and its such a relief to have found this channel. Alhamdulilah
Amazing lesson. Showing a very simple example after introducing the concept behind the method really helped my understanding. Really wish my teacher taught it in the same way!
I have a question. I think the m/z peak of 2-methylbutane at 72 should higher than pentane? why they are looking like the same in your slide. thank you
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?
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?
Fantastic explanation I was really confusing to learn mass spectroscopy U made it easy Can u please do all the A level topics in this way. Once again thankyou veey much sir😂😂😊😊😊😊❤❤❤❤
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 ?
For example in the problem the most abundant is 43 but in 43 there cannot be tertiary carbonation, so why tallest peak in 2 methyl butane????????? why is 43 tallest???
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?
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?
10 largest peaks in propane EI spectrum from NIST. 10 largest peaks: 29 (999 ), 28 (587 ), 27 (419 ), 44 (274 ), 43 (231), 39 (189 ), 41 (134 ), 26 (91 ), 15 (72 ), 42 (60 ) Compare this with the spectrum given in the video.

Meron G i can tell ur grammar teacher isnt doing u much justice either (ie. feeble use of semicolons and commas)

what a legend u are. textbooks and other videos make it quite confusing but you cleared everything up in one go. Much appreciated
I can´t belive somebody could explain it that easy. Thank you very much!

Simply outstanding!!! This is what real teaching is all about!!!

Superb explaination...I was struggling through the concept of MS now it's clear...thanks to u Sir
Incredible! I (re)learned not just about mass spectrometry, but also about chemistry and physics in general
As if Allah has sent an angel from heaven with all the info of mass spectrometer in this single video. I salute you boss. 😍😍😍😍😍😍😍
This is by far the best explanation on TH-cam
this is one of the cleanest explanations for anything i have ever heard
I am in love with this voice and accent. I just paused the video to comment this cuz this couldn't wait. Not to mention the explanation is excellent. Subscribed! ^_^
Wow! This is one of my favorite comments. Thank you! Maybe I should be a radio announcer.
Knowbee oh yeah! You should! You can also try doing audiobooks :D just let me/us(subscribers) know hahah cuz I'd love to listen!
What a teaching methodology sir .... amazing sir.... i have no words 😶
This is a masterful example of clear explanation. Bravo!
This helped me understand mass spec in just an hour . I’m really greatful for this video
Hands down, best explanation of mass spec!!
TOU'RE INDEED A WONDERFUL TEACHER. CONTINUE TO INCREASE IN KNOWLEDGE. THANKS A BUNCH
Beautifully explained! Thank you so much for finally clearing all my confusions on MS!
Finally, a worthy explanation.
Best video about mass spec ! So glad I found it
I think its just enough for each and every student. tnx sir
Does any change in molecular weight observe after forming molecular ion by knocking 1e away from it?
It's really great to have teachers like you who genuinely make a best effort to explain lessons like this. Thank you so much sir . God bless you 🙏.
Great way of elucidating complex concepts .Kudos.
thank youuuu. So glad i found your channel,, I was floating in my online class today morning and its such a relief to have found this channel. Alhamdulilah
Many many thanks, this video gave me a clear idea of MS. The explanation was so clear, informative, and simple.
WOW WOW WOW! THANK YOU!
It's so helpful when you break down the reasoning behind each thing. It helped me understand the fundamentals.
THANK U SM FOR BREAKING THIS DOWN INTO EASIER TERMS !!
Amazing lesson. Showing a very simple example after introducing the concept behind the method really helped my understanding. Really wish my teacher taught it in the same way!
Couldn't think of a better, satisfying explanation. Why didn't I find this video before!
I have a question. I think the m/z peak of 2-methylbutane at 72 should higher than pentane? why they are looking like the same in your slide. thank you
Wow.....you have great teaching methods! I will remember
remember the pool ball analogy....thanx!
From Egypt 🇪🇬 thank you very much
When breaking the bond between c-c to the right, shouldnt the carboncation that is generated be CH3CH2+ with molecular weight of 29 g/mol ? Thank you
A very understandable video under mass spec! Thank you.
Thankyou sir, i was really stugle with MS fragmentation, this course really help me a lot!
Wow!!👌👌👌very well explained about this topic🤗🤗Now I know more how to solve the ms graphs better👍 Always interested in it🤗Keep sharing
Thanks alot ..made everything clear in so easy way.. thanks again
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?
Very helpful video....thank you sir!!
I am having an online class right now in ms, but God damn it, I just learnt more from the first 9 minutes of this video than in the whole semester...
This was so beautifully explained, thankyou
This was an amazing explanation! Thank you :)
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?
Hey man you are a genius in explaining, hat's off
Fantastic explanation
I was really confusing to learn mass spectroscopy
U made it easy
Can u please do all the A level topics in this way.
Once again thankyou veey much sir😂😂😊😊😊😊❤❤❤❤
This channel helped a lot; thank you SO MUCH sir!!
there is a correction at 12.35..the carbon ( which hfragment of MW 28
) should have 2 H instead 1H
Wouldn't that make the MW=29 g/mole?
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 ?
When the electron from the electron beam is hitting the molecule, where does this electron go after the collision?
sir thank you very very much!! utterly grateful i found your channel sir!!🤩
awesome explanation
came to learn lc-ms. going with a degree in chemistry. hats off.
best explanation. love from Bangladesh.
thank you for your explanation it's very clear you explain very well
For example in the problem the most abundant is 43 but in 43 there cannot be tertiary carbonation, so why tallest peak in 2 methyl butane????????? why is 43 tallest???
The most best satisfactory explanation
Great explanation. However, when I searched the mass spectrum of propane, it showed that the most abundant m/z ratio was 29. Could you explain that?
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?
Thank you! Great visual of whats going on.
Easy yo know the mass spectrometer, thank you!
I learnt a lot from the video! thank you so much!
This is well explained, thanks Sir
Great video!! Couldn't get any better
How is the velocity measured?
You are amazingly amaazing, thank you so much. God bless you
Couldn't the 2-methylbutane lose its right hand side ch3 group turning it into an even more stable tertiary carbocation? @Knowbee
Why wouldn't the CH3CH+ (MW= 28 g/mol) have a 2+ carbocation charge since the C is only bound to two other things?
Thank youuuu so much! This has to be the best explanation of MS.
Why doesnt carbocation rearrangement takes place?
just awesome crystal clear concept thanks
Excellent explanation ....absolutely understandable thanks 🙏
Great video, thanks so much!
What if we inject there 3
Or 4 compounds?
Nice job explaining the subject, I kinda missed the mention of Isotopes which would also be visible on the mass spectra.
isn't there a possibility for the primary carbocation in pentane to rearrange?
What if the beam knocks out 2 electrons? Then what happens?
Thanks
It was dope sir❤❤❤
Great video, is there material on your site explaining primary and secondary carbo-cations and what the difference is?
Excellent ❤️👏🏻
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?
