Thank you so much for his video! I have my organic chem lab tomorrow and we're going to do this very same reaction and I feel a lot more prepared thanks to this
Note to self questions: 1. Why are anti-bumping granules used? 2. What is the purpose of re-distilling? 3. What are all the reasons that your will not get 100% yield for your product 4. Why should distillate collected be put on ice bath? Prevents product from evaporating, increases product yield
idk if this is correct so correct me if im wrong but sulfuric acid alone causes both oxidation & polymerization to occur. phosphoric acid is used as the dehydrating agent and it works betters, it just happens rather slow which is why its used over sulfuric acid
What's the by-product in the reaction vessel? I have a similar condition when running the experiment. (Some of my classmates even have some impurity in the collecting vessel.)
When the bromine water reacts with the cyclohexene, does it result in the addition of trans Br and OH from a Halohydrin reaction or a trans Br and Br from a Halogenation reaction?
Hi Emily! It is Halogenation after researching. I could see how one would have thought about Halohydrin because of the water component in the Bromine solution.
Can anyone clear me with the answer of this questions please? why the temperature on the top of the fractional column during reaction be controled? and why being added salt before the layers are separated?
hey the answer on your first question is because cyclohexene has actually a boiling point of 83 °C, so that’s one point why you check up the temperature when you see that it reaches on its 80-85°C that is where the destillation actually begins, and during your destillation you need to the check the temperature because afterwards when your temperature drops down again, your destillation is finished. The answer on the second question is because before putting the salt you have a mixture of water and cyclohexene and actually the density of both are nearly the same, so you wouldn‘t be able to really see two different layers, after putting the salt and shaking it you can clearly see 2 different layers, the bottom the aquaeous one and on the top the organic one which is indirectly your cyclohexene. I hope that my explainations helped you and that i answered on your questions pretty enough:)
Thank you for the video. Very useful to use with students during lock down. Excellent teaching points.
Yes, my professor is making us watch this too.

You did a great job explaining the experiment and discussing the process. Thank you for taking the time to make this video.

This was super helpful. I feel like I comprehend this lab super well now. Thank you!
His voice is so pleasant
Thanks sir, it helped a lot. May God bless you abundantly.
Pretty useful thanks!
Thank you sir, this video was extremely helpful and each step was explained clearly 👍😊
Very informative and wholesome video!
His voice is so calm
Can you be my professor . This is such a great video , thank you professor mccartney .
Thank you Doctor that was beautiful
Excellent explanation 👍🏻👍🏻
Thank You so much sir for this video,it helped me a lot and i was able to understand this experiment pretty well
Thank you so much this was very helpful!
Thanks!!!
thanks so much i had an exam and this helped a lot
THANK YOU
Thanks
Thank you so much for this video
betam new mamesginaw dear technician
thanks a lot, it helps me
Thanks a lot

Prevents product from evaporating, increases product yield
thank you very much sir! would you mind answering my question? why did you choose phosphate for the catalyst over sulfate acid?

Calcium carbonate as drying agent? Not really effective… how should this work? CaCl2, CaSO4, MgSO4, Na2SO4 would have been better options…
thank you fo rthe video, would you be able to post the sheet that you used that had the instructions ?
👌
did this experiment twice and both times was a failure
thanks very much

yo no hablar taka taka
shivesh said u are slow at explaining things
