Mass Spectrometry - Fragmentation

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!

[@azlyfarah6198]

thank you so much. I watched so many videos to understand this concept but u made it sound so simple

[@BoomShax123]

Thank you so much my teacher can’t teach and you taught me how to do this in 12 minutes. 👏👏👏

[@jojowolfie1839]

Your videos are life changing I swear. Thank you so so so much

[@aliarafique6231]

God bless you, you make my concept very clear...Thanks.

Hii

[@saynabomar6056]

My exam is in two hours thanks!!

[@AlleryChemistry]

Hope it goes well for you! Read the questions carefully!

[@sithangahansana4979]

How did those exams go😅. What are you doing now

[@anastasiarodana8766]

Thank you for making fragmentation such an easy process! Bravo for your explanation !!!!

[@Angela-gs1cp]

your videos are so incredibly helpful

[@AlleryChemistry]

Glad you like them!

[@mikehillz2613]

nice and simple explanation . thanks

[@theeverlastingfather1111]

Really, it's a supportive stuff; thank you bro.

[@ainnadzirah6982]

Thank you, it's very helpful! Keep it up!

[@AlleryChemistry]

Glad it helped!

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.

[@rajanivgv2806]

Very properly explained.Superb video....

[@AlleryChemistry]

Thanks! Please share, the more people use this channel the better! 😀

[@ally4486]

Excellent video, Thankyou.

[@fatimahislam792]

Very informative and helpful!👍

[@shrutishete6456]

simple and nice explanation. thanx a lot sir !!

[@AKshay_47]

Nice one bro....

[@parasgupta38]

nice video!! very clear..just one question
can ch3ch2+ further break into ch2+ and ch3 radical ?

[@AlleryChemistry]

Yes it could. The whole fragmentation process is random.

[@niralee2611]

is this on the aqa spec, your videos are my holy grail btw

[@adnanmahmud8691]

Can the carbon be broken from hydrogen?

[@ardisrexha868]

is this needed for the new spec?

[@joebloor1413]

I dont think this is in the AQA spec anymore 2018?

[@umaymahmiah3259]

thank you !!!!!

[@AlleryChemistry]

You're welcome!

[@mollypass6292]

Would the molecule only ever split at carbons?

[@nourelhouda6330]

pleas i need an explanation of sims secondry ion mass spect. very Nice explanation btw thnks very much ☺

[@AlleryChemistry]

What do you mean sims secondary ion?

[@missghani8646]

thank you so much

[@hanxiaozhang1499]

thank you thank you than you very much!!!!

[@AlleryChemistry]

You're welcome!

[@keeweeow624]

Can just one H be broken off?

[@alexiaplacinta5468]

Do you offer private tuition

[@ksi800]

Might be a stupid question but when you have OH+ its because its lost an electron, so it really isnt OH?

[@samhasamed1857]

Hey, is this needed for AS level syllabus?

[@AlleryChemistry]

What spec? Most will do this in Yr2 rather than AS though.

[@samhasamed1857]

Thank you :)

[@ar-mo7xc]

Is this aqa?
