Hi everyone, I'm excited to announce that I now have posters available for the reaction schemes in this video: Aliphatic reactions: rdbl.co/47y5oAk Benzene reactions: rdbl.co/41W1qQM Phenol reactions: rdbl.co/3NZc8QE Perfect for learning organic chemistry (and supporting the channel at the same time!) 👨🔬
Thank you Chemistorian, your videos are undoubtedly the clearest and most accessible explanations of a fantastic range of topics. I am sharing as many as I can with my school chemistry department. I have certainly learnt plenty too.
I kept an entire instrumental laboratory in work for over 2 years. Thousands of compounds underwent GC/MS & NMR which combined allow one to fully elucidate the absolute structure of many organic compounds. However, optically active compounds required an extra step - polarimetry. It was evident not many people asked for this because they had to ask ME what form of polarimetry I wanted. That was a little disappointing. I inferred that while they did a GREAT job at both the GC/MS and NMR, they didn't bother to work out what the compound actually WAS. It makes sense, I suppose. They were paid to provide instrumentation, not to interpret the results. What did I learn? Never trust Chinese labs. If they CAN rip you off, they WILL rip you off. I refused to pay when the compound wasn't as specified and sent the GC/MS and NMR data to prove they hadn't produce the product... but a few would still argue the toss. Now I don't know if that was bad chemistry OR a management whose business model was to just try to get away with it based on enough people paying and just not using them again. Seems like a bad long-term strategy...
Hey I might just be confused, but if you repeat an event with a certain chance you wouldn't add the precentages together, right? So the formula would be 1-0,989^(5)= 5,38%
Thanks for sharing this video, I have a question, when measuring CO and N2 with the mass spectrometer, is there a way to differentiate them, using a mass spectrometer?

Why does this not have way more likes and views!?? Its a really great explanation. THANK YOU for making this video!
Couldn't have asked for a better video to explain Mass spec.

Amazing video! I never leave comments but this video helped me a lot with my exam, thank you!!!!
great video!

Fantastic, thanks!
I am understood nicely thank u very much sir

please make some video on absorption and emission spectrometry

may god bless u for the vid
Great expanation. Why couldnt a molecule be broken in an C-H bond?
They can! Many of the peaks you see could be due to a fragment which has lost a hydrogen atom (or multiple hydrogen atoms).
Okay, i didnt get a bit of what you were explaining,could you simplify everything after "Hello"
