Mass Spectrometry Fragmentation Part 1

[@Sky-pg6xy]

“Lets learn how to do it, and do it quickly” What a pro.

[@mrobireonomewilliams2998]

Thank you sir... Read my books and I was confused this video just made my day. God bless you... I will need videos on IR and NMR

[@christinalatsko3525]

This is the most helpful video I have EVER watched for organic chemistry. You really make it straight forward, and explain things clearly. Thank you.

[@pavankumarsingh7953]

No one can explain better than this....... One of the best video on MS Thankyou knowbee

[@Knowbee]

Thank you for your very kind compliment!

[@jakehauhnar8462]

this is better than class...im gonna share this to all my classmates...

[@manajanasena1461]

Haiiiii sir I'm following your channel from 4 years Sir you are tooo great..I don't know how to explain my happiness on you sir...Today i got good command on Spectroscopy that's only because of your lecture.. Your teaching way is awesome 😃😃😃😃 feeling happy I became a student of you sir

[@evanie1159]

I dont know a more proper way to thank you!!!!! You have helped me understand fragmentation in a very clear, simplistic manner!!!! Thank you so much!

[@iliasjamouchi7333]

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

[@favourifezue1201]

Thank you for this I got confused so i had to check the comment section

[@sasukeuchiha5391]

Hat's off sir.... superb explanation Nobody can explain like this on whole KZbin.. Thank you very much...

[@AminAhmedtour]

Thank you for such great and understandable explanation Dr.

[@Knowbee]

You're welcome! Thank you!

[@asiaeamdani2054]

i dont care how old this video is, but amazing!!! Ur helping the future man, keep up the goood work;)

[@nurfatanah8675]

masa study degree dulu..xfaham lansung konsep fragmentation in mass speck..but thanks to you my understanding about fragmentation was crystal clear

[@studysgood5027]

I like it well explained keep on such quality forever. ..plz..

[@reemakhalid5424]

From the bottom of my heart, thank you🥹💜💜🌸

[@a.a.2752]

really appreciate the tidbits of reassurance and encouragement midway because it definitely was starting to feel overwhelming but i am glad to say i am leaving with better understanding of the topic so thank you !

[@josefsadki7158]

I agree with you Andrew 100%

[@khathutshelo2874]

Top site great explaination, thank you.

[@jdftba4164]

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.

[@piyush7349]

Best explanation on could get on this topic 👍👍👍👍👍👍👍👍👍👍

[@dr.shaileshkoradia6691]

Very good video for understanding of mass fragmentation

[@pooja2153]

Thank you so much You made this look very easy

[@adamsilvester978]

Excellent video! Excellent delivery and easy to understand but McLafferty rearrangement?

[@chemlerner]

Very good explanation

[@oukournabil]

Since i ve seen this video i decide to subscribe in ur channel

[@muafiamushtaq7080]

Nice explanation... Just saved my time.

[@kajolhanchate1715]

This video saved me ❤

[@esmeralda_jenn]

Perfect explanation! You helped me a lot! iPerfecta explicación! iMe ayudaste mucho!

[@Knowbee]

Great! Good luck in all your studying!

[@daliaalfaris763]

Knowbee hkkj

[@fatmareber7189]

Vielen Dank,♥️this vid save ma life XD

[@GodlikeIridium]

Or the lazy answer to the question: No m+2 so no halogen. So it must be the third one. Great video easily explaning ms interpretation!

[@Gabrielaanm]

Thank you so much for this video, helped me a lot!

[@justsnob]

Brilliant!

[@hussaian143]

Good explanation.....it is helpful to competative exams

[@mortazam.qassem5194]

You're a godsent

[@akeedasharma4249]

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]

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.

[@kotamariyababu6515]

Very helpful video.thank you so much

[@v.smourya8005]

You just saved my SEM exam boy !!!!! :D Thank you very much :P :) ... tomorrow's my chem exam :D

[@Knowbee]

Wow! Glad I could help on the exam! Good luck on all the rest! And thanks for the compliment!

[@v.smourya8005]

I would have definitely failed but i scored far more than i expected ... 72/97 :O ... Once again Thank you @knowbee :) :)

[@chemmuhammadasifsheikhsult844]

Very nice deliver of lecture

[@animeshmukherhee7036]

Fantastic explanation

[@anthonychoyo9203]

Thank you so much, Sir. This helps a lot .

[@Nobody7011-i6h]

Thank you so much

[@zeeshanqasim8925]

If the fragmentation products are not initially identified, then how do we will decide about them, when we are seeking the ecotoxicity of parent vs daughter compounnds

[@zareaalzarea836]

your work is great, but you need to change the colors to something else not gray and green thanks

[@Ga3meRAdr3]

underrated

[@Master_mindians]

very well explained sir..Thank u very much

[@Knowbee]

You're welcome! Thank you!

[@shi5702]

thank you thank you ;-; i didn't understand anything from the textbook

[@mahmoudsamaha8256]

you are fabulous man !!

[@romulus2225]

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?

[@mbalenhlemthembu4147]

Thank God i found you. 😘😘

[@Knowbee]

Thank you!

[@shaniyazehra2900]

Hey ... please can you tell me the reference from where you bring the content?

[@fhdjdnfjfkcbfjdndn4827]

00.36 am and im about to cry of happiness

[@canipoo]

that's rookie numbers

[@mr.lonely2825]

thx man ur the best

[@fjrfree]

What if there's no halogen in the structure? Which of the electron that gonna be beam?

[@lunbabuichiru6320]

brilliant

[@gilmor1]

God bless the teacher 🙏🏾

[@TheDeevanesh]

at 15.14..... in alpha cleavage..... there should be 4 electron on chlorine instead of 5. after fragmentation

[@Knowbee]

You are correct, sir! Sorry for the confusion. And thank you for the clarification.

[@Realeyeiz]

thank u so much sir... your official website is close.. plz help where can I get the full course with notes

[@hussaian143]

plz sir concentrate on mclafferty rearr. of ESTERS & ACIDS

[@vvvvv800]

God bless you

Thanks man!

[@yarubandiprasad319]

Where is the butyl in s-butyl isopropyl ether

[@mohammedhassanelsayed7563]

please can you help me at fragmentation of isopropyl isobutyl ether?

[@ramden2002]

Can u please explain x Ray crystallography

[@st.chemist]

perfect

[@yarubandiprasad319]

Instead of ch2 we should write ch3 at the starting stage

[@baileyedmonds1080]

how would terephthalic acid fragment???

[@goutamdebnath1427]

সেরা।

[@pamplemousse5546]

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]

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.

[@pamplemousse5546]

Thank you!!

[@debebebirhanu3256]

any best book you can point me thanks

[@asmaramzan1110]

👍👍

[@spark-sp-avb2548]

Thanku sir

[@Alrukitaf]

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.

[@ardenharan2201]

Excellent video, very helpful. Also, you said "cleavage," tee hee hee.

nice

[@areejowais9115]

الشرح كتير ممتاز بس ازا في مجال تعمل شرح للspectrum كلو مثلا كيف بصير فقدان للماء بالketone or ester وكيف منفقد الCO في المركبات ؟؟

[@серыр]

Good afternoon! How to contact you?

[@Knowbee]

I just added how to contact me in the description.
