Electrophilic Aromatic Substitution

The mechanism of electrophilic aromatic substitution and the effect of electron withdrawing/donating substituents. What better way to elucidate substituent effects on the doughnut cloud of pi electrons than by comparison to actual doughnuts! Featuring Homer Simpson as an electrophile (doughnut-phile).

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

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

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

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

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.

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!

Great job. Students relate to doughnuts!!

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

Very helpful! Understood everything! :)

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

Thanks Homer !

Mmmmmm Doughuts! Thanks you are a genius!

nice video. good concept. easy to remember.

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
