Electrophilic Aromatic Substitution

[KanzakiGNT]

Man you sound like you'll fall asleep in the middle of your phrase at any moment!! :D

[ojay12341234]

@KanzakiGNT lol I was just gonna say that

[jadeolay]

Very helpful! Understood everything! :)

[ayyjay69]

a rather unsweet pastryyyyyyyyyyyyyyyyyyyyyy

[ayyjay69]

Your video says Electrophilic Aromatic Substitution, but your tone says Seductive romantic substitution

[zanahoria29]

Thanks Homer !

[sgomez131]

Mmmmmm Doughuts! Thanks you are a genius!

[kaushiktlk]

nice video. good concept. easy to remember.

[PLUNKATAMI]

Isn't the hal+ attacking the benzene ring, creating so called PI Complex then the aromatic system breaks, because one of the C-atoms is in SP3 hybrid state and you get the Sigma Complex. Then a proton ( H+) leaves the complex, reacts with the FeHal4- and the final products is created and H-Hal also and the CAT renews. I am not a college student, I just like chemistry, btw first english chemistry comment. :P

[Rollerxpert]

Besser als Herr Bischof's Unterricht!

[wranglers575]

Good video!

[bodinian]

Dough-nating electrons to doughnuts.

[bodinian]

What kind of doughnut would you call trinitrotoluene? I am guessing it would be like a cement doughnut of death.

[wranglers575]

@bodinian A stale doughnut covered in soy source :P

[jfettig2012]

Thank you so much for posting this video! It is a great tool for visualization and understanding EAS! : ) Much appreciated!

[daytona712]

th inunderstandable XD has been understood!!LOL

Thanks

[femilyrpy]

thank you thank you thank you!

[MONKFOCKER]

Dude you are dull.

[chemjeri]

love it, will show my students for sure!

[salemr86]

"2 things have gone horribly wrong for this benzene ring..." ha ha great video. Very clear.

[candaxen]

Excellent!

[echizennami14]

wow this is very nice i actually feel the enthusiasm to learn more! x3 thanks for the vid :3

[Sorcery10]

lol good job, yuck bran muffins

[salemr86]

this is so awesome ha ha brilliant

[jattatheart111]

college students are so lucky this day and age, they have the internet/youtube to learn organic chem. back in the 90s when i was in college we had to read an incomprehensible book in a course taught by an uptight professor. WOW

[wolfram184]

hahaha! Well, it is fun to take advantage of the technology that's available. Regardless, the old fashioned repetitive problems still have their place:)

[captainplanet999]

@wolfram184 woops didnt mean to thumbs down ya

[alexanderb33]

@jattatheart111 Not necessarily, outside of Chemistry/Organic Chemistry and focusing more on the other scientific fields of study (more so medically related than anything else), the college students of "this day and age" have a significant amount of newly discovered information to learn compared to the past. Biology, Biochemistry, Pathology, Pharmacology and Human Physiology have evolved a great deal during this era of new technology. But I will agree that the internet helps us ALOT.

[captainplanet999]

@jattatheart111 you'd think so, but teachers nowdays are getting worse and worse. where i go to school my teachers are kinda lazy and all the homework and what not is outsourced to third parties. that and its no different than what people were doing 5000 years ago

[captainplanet999]

@jattatheart111 but yes technology is awesome =)

[KierstenKay]

OMG, that was too cute and I really understood it, ur great!! Thank you!!! =)

[ac135]

good stuff man, thanks

[arulinidavid]

thank u

[reclusivesage]

What kind of effect does methyl benzoate have? Inductive or resonance?

[nanotech71]

I wish all use these methods in different topics.

would make scary topics actually fun...

[ButterflykiSS811]

Very helpful indeed! Thank you for such excellent way to remember these reactions! It is amazing how you came up with this!

[EnigmaticMayur]

very nice explanation

[SunnyPhillyRuleZ]

I am craving for doughnuts now. DUH!!!

[soadj28]

Genius, where do you teach?

[sukalubov666]

THANK YOU SOOOO MUCH!

[pyrovampcat]

thank you this is really helpful for studying for my chem final!

[mlcarrol]

Great job. Students relate to doughnuts!!

[omerahd]

That was awesome!

[Iceteatropicalfruit]

lol wtf.. this actually helped me

[paopaomanalansan]

Thanks so much! Now I fully understand resonance effect in aromatic compounds.

[SushiSocks]

This is beautiful. A clear and frankly unforgettable explanation of electrophilic aromatic substitution. This chemistry student is very, very happy. And hungry for doughnuts.

:)

[anvoodoo]

oooh i love it!!! this is way better than OChem for dummies and i don't even have to try to remember it /study it. now it's stuck in my head w/ homer's image! thanks so much!!!

[entadus]

Very nice video, we're covering this in class this coming week

[winterwind23]

Very informative and entertaining video!

[kittythecakes]

that was awesome

[sigma1721]

LOL you´re a Genius guy, good video. Who say that youtube don´t educative?

[owensr4818]

wow....

[EdwardNavu]

"D'oh! What is this?! R- deactivating?!"

I can see it completely!

[amirkhayn]

I just wanna say thank you, I am a chemical engineer, and these are very usefull, keep up the good job.

thanks again

[BigPurple121]

This guys voice gives me the creeps. Thanks for the video though

[thisusersuck]

TY you 'wolfram184' i have to do a prestation on reaction of benzine and i might use some of the homer stuff

[reclusivesage]

This is great stuff. Organic chemistry is really fascinating, but I've found the way it's taught to be as dry as everyone warned. Your doughnut analogy is the first time I've seen creative teaching in this subject.

[TheFluorineMartyr]

Dearest Wolfram184,

Nitration of Phenol (dil HNO3) => o,p-nitrophenol

Nitration of Phenol (conc HNO3) => "TNP"

However will nitration with concentrated HNO3 cause oxidation? and If so what would this oxidation product be?

Cheers, you'll have a better idea than me!

[superman96021]

nice work.. Ur so awsome

[FalconX88]

Real good work!

It's very good to understand the theory!

[cigiss]

i love this so much, thank you thank you thank you!!

[bigfatdinq]

LOL!!! Bran muffin/nitrobenzene analogy....

Thanxs alot!!!....helped me better understand the basics!!!

[krustenhund]

this will help me a lot to remember

+/- I/R

thanks!

unfortunately now i'm hungry :)

[Conquest215]

"Mmmmm.....sigma complex". lol

[wolfram184]

Thanks-hope this was helpful for you. Best wishes-LET

[jaytheman898]

Have to agree with everyone else, this is is a great vid, love the analogy. Hint hint if you were to make a dvd I would buy it.

[wolfram184]

Hi,

thanks for the kind remarks. I hope to get lots more out. I'll keep putting them out, but this is for free. I am not impressed with textbooks and am trying to connect through youtube. glad you enjoyed it and thanks for your comments!

[latrelle2004]

This is great. We're discussing this now in Orgo 2. Thanks for the vid! I wish there were more!!!

[wolfram184]

Hi-

thanks for the feedback.  I'm working on more, just cant make them fast enough! thanks for your kind comments it makes it worthwhile for me!

[durranim]

shit....so thats what its all about....now i can never forget the concept...awesome job...only if everything could be tought like this.

[wolfram184]

Thanks for your feedback. Glad you found it helpful. Its difficult to find useful analogies for this stuff but I'm glad this has helped you. Thanks for taking the time to comment!

[thehotdelancey]

As a fat man, 100% more exciting than how my current professor talks about it.

Why do we have to pay 12K+ for a UC education when everything we need is on Youtube!!!

[wolfram184]

Heehee, thanks for the feedback. I do enjoy making them and hope to have more out soon. Thanks!

[ziad4]

Amazing. But I wish you could higher the voice a little bit.

[wolfram184]

Thanks-I'm still working the bugs out of my audio, it is a bit weak unfortunately. Glad you liked the video. Thanks!

[schmerikon]

good job! my prof taught me pretty much the same, but clearly not in such a vivid way :D

[wolfram184]

cheers for the feedback. I'm in the early stages of a more complete library but am very encouraged by the responses! thanks

[wolfram184]

Thanks! Glad you enjoyed it....anything particular that you like about the video?  Thanks for your comment!

[bevthomson8]

splendid

[wolfram184]

hanks! Glad you enjoyed it....anything particular that you like about the video? Thanks for your comment!
