    Hey sir, would you be able to go through trickey RDS steps especially those when there are charges involved, I am always stuck at those

    Hi teacher. Could you please make a video about how to differentiate E and Z isomers in NMR? It would be very useful

    By far the best explanation I’ve seen. Thank you sir! Also your video on blood buffers came in clutch for paper 1 🙏🙏🫶

    Hi sir, I haven’t commented before but I just want to let you know I watched this video this morning 20 minutes before the exam. I’ve never ever gotten an NMR question right but a very similar question came up and I’m confident I’ve done it well. Thank you.

      That’s excellent news - I hope it went well 👍🏻

    4:10 how can u tell it’s an aromatic peak just by looking at it?

    • @mrmurraygreen
      @mrmurraygreen  6 місяців тому +2

      Good question!
      Its position on the chemical shift scale and the very distressed splitting it has doesn’t follow a clear ‘roof’ shape like other peaks do. (i.e. other peaks go to a point in the middle using their splitting pattern)

    This is such a random question, but can you do a tattoo tour, I occasionally see your tattoos and they looks so interesting. Sorry for awkward question.

      Hey 👋 I like this idea! Although they have a mix of stories (or total lack of story) behind them 😅 I’m getting a new one in Sept, I’ll do a montage once I’ve had that one added 🔵

    Hey sir wouldn't there be 5 proton environments in total as the cooh signal is missing from the nmr? So would the final structure only have 5 proton environments? I know I am wrong but wasn't sure why.

    • @mrmurraygreen
      @mrmurraygreen  6 місяців тому

      The final structure needs to have the peak which is removed by the proton exchange added back in
