    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!) 👨‍🔬

      Great to hear! Once you understand, looking at spectra can be kind of fun (in a very nerdy way). It's like solving a puzzle 🤓

    I really wanted to thank you for this clear and concise explanation. I have my O-chem exam in a couple of days and for the life of me i couldn't figure out how to piece together a molecoule from a specter and vice versa. I knew all the teoretical bits about stretching and HOMO and LUMO but this practical part really puzzled me. Thank you for your part in educating the future chemists of the world and keep up the good work!

    Thanks a lot for these lessons!
    Trying to solve the last example instead of -CH2- I've initially assumed a =CH2 group at an end of the molecule and, after trying crazy (C2O2) heterocycle, I came to this: C2H5-C(=O)-C(=CH2)-O-CH3. Of course, I think, this molecule is much harder (if possible) to produce than hexane-2,4-diode and it does not explain abnormally small electron cloud density around the CH2 group.

    At 17:36, could you please explain why the multiplet is a septet. Shouldn't it split to 9 peaks?

    • @Chemistorian
      @Chemistorian  Год назад +4

      Great question and you're absolutely right. Well spotted! It's only like that because I was drawing these spectra manually, and they're quite fiddly to draw, but if I had more artistic ability, it would be split into 9 haha

  • @dantefernandez2455
    @dantefernandez2455 6 месяцев назад

    I'm late to the party, but for the last problem, wouldn't a cyclopropanone with a methyl group and ethyl ether on one carbon also work? 6 carbons, 10 hydrogens, 2 oxygens, and the NMR matches, unless I'm wrong and the first singlet would be more shielded than a regular ketone due to the inductive effect of the ether group?

  • @ugochiokii8844

    hi, I have a question for the proton nmr at 13.02 how is it split into 4 environments when none of them are in identical environments?

    • @Chemistorian
      @Chemistorian  Год назад +1

      It's quite hard to spot, but the two CH3 groups on the left hand side of the molecule are equivalent to each other. They're both CH3 groups coming from the same carbon atom, making them identical environments.
      That gives us 6 protons all in the same environment, which is why the peak on the spectrum for that environment has an intensity of 6.

    • @ugochiokii8844
      @ugochiokii8844 Год назад

      Thank you so much for replying
      um I was actually asking about the beginning part of proton nmr where you said just like 13c nmr we can identify that there are 4 environments my question is how is it 4 environments? Is the molecule not an ester. I am kind of confused about which part of the molecule is an identical environment @@Chemistorian

    • @Chemistorian
      @Chemistorian  Год назад +2

      The spectrum that shows at 13:02 is for isobutyl acetate. If you keep watching, I explain how to assign all the peaks in that spectrum. You can skip to 19:05 to see the final structure once I've gone through all the peaks, and I highlight the protons which are in identical environments to each other. Hopefully you'll be able to see that there are only 4 proton environments for this molecule.
