Synthesis of Cyclopropane by the Wurtz Reaction
In this video I prepare and condense cyclopropane, the smallest cycloalkane. The procedure was made up as I went along, roughly based on examples of the Wurtz reaction in Vogel's Textbook.

    hello, sir thanks for the insights you provided from this video I had a doubt about the above as I have tried making a deep eutectic mixture of the same but was unable to get any similar results my insights were as follows : 1. the eutectic was formed but had a yellow tinch but it was overcome by using a good quality of urea 2. the next problem is that the des was made but lasted for few seconds only and after that it was recrystallized and was stuck to the beaker I need your guidance for the above to help me in my research work your inputs are valuable to us . i would also appreciate if you can provide me a mail id for contact .

    I think that every student of Organic Chemistry should learn how simple it is to do this procedure properly. Another Catalyst that would be useful is Adams' catalyst, or simply the Platinum Dioxide that has not been reduced to Platinum Black, but is reduced in situ with the reactants and Hydrogen.

  • @CondorrK

    Hey Tom, Ive been having trouble with my hood door and I like the way you split yours. Unfortunately I'm on a massively tight budget and limited tools. I can split the plexiglass but trying to assess how to mount them so they slide AND stay in place the way yours does. My other issue to resolve first is my wood is bowed, lending further to my problems lol. Do you have any advice? I almost went with a motor driven pulley system but that would compromise the seal and kill my face airflow

    • @CondorrK
      @CondorrK Před 6 měsíci

      It might also be notable, I'm using lightweight materials so that it's more easily portable since I'm in shared living quarters and all. I don't find much issue with smell or anything with my tests of the air system but I'm afraid further reinforcing the sides and possibly allowing for a proper fume hood door fitment would need more permanent space to stay. It's made of 1x0.25" wood beams and mylar walls with a plexiglass door and the most inert caulk I could find for sealing
