Heterocycles Part 1: Furan, Thiophene, and Pyrrole
Вставка
- Опубліковано 21 лип 2024
- We've mentioned heterocycles before. They are cyclic molecules where one or more atoms in the ring are not carbon. Typically these involve oxygen, nitrogen, and sulfur. But there are so many different heterocycles. Different sizes, some aromatic and some not, and many of them are important for synthesis. Let's look at a few key heterocycles now, those being furan, thiophene, and pyrrole.

This has been a challenging but gratifying series, Professor Dave. Your homework assignments keep me on my toes!
LOVE brushing up my basics with Professor Dave!
Amazing organic chemistry understanding 😁😁😁😁😁
Hi Dave we want to know how heterocyclic compound degrade in aqueous environment and how to avoid them...also want to know degradation pathway
I spent almost my whole night searching for explanation of the order of aromaticity of these prominent heterocycles. I am glad I have come to my bus-stop. I have learnt that the order depends on the resonance stabilization energy. Benzene>Thiophene>pyrrole>Furan.
Didn't he say in the video furan is more reactive than benzene
I can't get over how you decided to upload this at the time right after I attended the lecture for diels-alder reactions & aromacitiy.
It's like you know somehow that 2nd semester Orgo students are being taught aromatics at this exact moment.
I'm just curious; how'd the rest of your class go?
Yo Dave could you do more biochemistry videos on metabolism?
Hello Sir Dave, can you please make a video on Sanger Coulson DNA sequencing method?
Love your content dude and really enjoyed your chat with Aron and his wife the other night. Have you considered or would you consider doing a colsb with conspiracy Catz? He like you is a science educator, UK rather than US and I think you guys could do something awesome.
this video did help me so much, thanks professor :)
Thank you soo much! I've passed my organic chemistry course in uni thanks to you!
Way to go!
Thank you prof. Dave
Thank you for the properties that i didn't knew about them😃
Thank you professor Dave
Go ahead
Your work is appreciable.
Truly you are a among chosen people of god.
Very well explianed
can the oxygen in furan use its unused electron pair to attract a proton?
This 7 seven minute video is more useful than a whole hour of my professor's lecture. Learning this on the last day of my exam. God save me.
How'd the exam go?
@@PunmasterSTP Its 8 months ago I forgot 😂
@@guywithakeyboard Haha, that’s alright, as long as you keep on going!
Thanks for the amazing explanation
2:50 could you pls expand on why resonance can’t occur if E is on C3? As far as I can see, neither system is conjugated as both contain only 4 pi electrons?
I remember becoming furantic shortly before ochem tests, hoping I would thiophinish. I was also arrested for making a bunch of lame puns, but eventually I was let out on pyrrole.
😎
Mid
@@kissalasoruvudhukannu That’s just how I pyrrole 👍
@@kissalasoruvudhukannu Let's C you do better!
Better Knowledge and Understanding than what a Whole University could teach
Thanks Professor 🙏🏻✌😌
Can we get monobromo derivative of pyrrole by any means
Nice explanation
Wasn‘t there somethinh with the protonation of pyrrole? We were taught that the protonation also occurs on the C3. But one of the protonation reaction can undergo a ring opening reaction. Idk, I haven‘t really understood it, so that‘s why I‘m here.
Aren't heterocycles the ones with the crossbar?
Prof Dave can you explain more about pharmacology or the krebs cycle in biochem? Im having a hard time with biochem and pharmaceutical analysis right now.
I cover the Krebs cycle in my biochemistry playlist and I also have a whole pharmacology playlist!
@@ProfessorDaveExplains Oh thank you Prof, youre a life saver🥺🥺 never knew pharmacy school could get this hard 😭😭😭
thank you
Love your work and videos. Please stop by Abiogenesis on Facebook- your videos have been shared there numerous times. And we all love your battles with creationists. Keep up the great work.
But why only one pair of free electrons of oxygen or sulfur considered as delocalized electron? Why total pi electron is not 8?
very nice
What a intro😍😍
Greaaaaaat.... U r great 😍
morn'n Dave
Professor, please make more videos about Italian language and please create a playlist based on German language
Wow thats cool i had a presentation on furan a months ago
ma hada bi hemo
I have a exam on this topic and here is my favourite professor's lecture explaining the concept !!.
Thank you sir
How'd your exam go?
Heterocyclic based acid name
Aye aye professor
What who even has carbon tetrachloride outside of the US air-force?
Explosions&Fire 💙💥
love uh
Thank you sir, you are amazing.
Regards.
Lots of respect from Pakistan.
I know some of these words.
Can i call you captain America?☺️☺️..
You look like infinity war look of captain!!☺️☺️❤️❤️❤️❤️
currently in high school kids...
Fun stuf
*common sense has left the chat*
Why ???
first comment
Ok im second
Early be like
